-gRPC in 3 minutes (Go)
-======================
-
-BACKGROUND
--------------
-For this sample, we've already generated the server and client stubs from [helloworld.proto](https://github.com/grpc/grpc-common/blob/master/protos/helloworld.proto).
-
-PREREQUISITES
--------------
-
-- This requires Go 1.4
-- Requires that [GOPATH is set](https://golang.org/doc/code.html#GOPATH)
-```sh
-$ go help gopath
-$ # ensure the PATH contains $GOPATH/bin
-$ export PATH=$PATH:$GOPATH/bin
-```
-
-INSTALL
--------
-
-```sh
-$ go get -u github.com/grpc/grpc-common/go/greeter_client
-$ go get -u github.com/grpc/grpc-common/go/greeter_server
-```
-
-TRY IT!
--------
-
-- Run the server
-```sh
-$ greeter_server &
-```
-
-- Run the client
-```sh
-$ greeter_client
-```
-
-OPTIONAL - Rebuilding the generated code
-----------------------------------------
-
-1 First [install protoc](https://github.com/google/protobuf/blob/master/INSTALL.txt)
- - For now, this needs to be installed from source
- - This is will change once proto3 is officially released
-
-2 Install the protoc Go plugin.
-```sh
-$ go get -a github.com/golang/protobuf/protoc-gen-go
-$
-$ # from this dir; invoke protoc
-$ protoc -I ../protos ../protos/helloworld.proto --go_out=plugins=grpc:helloworld
-```

-#gRPC Basics: Go
-
-This tutorial provides a basic Go programmer's introduction to working with gRPC. By walking through this example you'll learn how to:
-
-- Define a service in a .proto file.
-- Generate server and client code using the protocol buffer compiler.
-- Use the Go gRPC API to write a simple client and server for your service.
-
-It assumes that you have read the [Getting started](https://github.com/grpc/grpc-common) guide and are familiar with [protocol buffers] (https://developers.google.com/protocol-buffers/docs/overview). Note that the example in this tutorial uses the proto3 version of the protocol buffers language, which is currently in alpha release:you can find out more in the [proto3 language guide](https://developers.google.com/protocol-buffers/docs/proto3) and see the [release notes](https://github.com/google/protobuf/releases) for the new version in the protocol buffers Github repository.
-
-This isn't a comprehensive guide to using gRPC in Go: more reference documentation is coming soon.
-
-## Why use gRPC?
-
-Our example is a simple route mapping application that lets clients get information about features on their route, create a summary of their route, and exchange route information such as traffic updates with the server and other clients.
-
-With gRPC we can define our service once in a .proto file and implement clients and servers in any of gRPC's supported languages, which in turn can be run in environments ranging from servers inside Google to your own tablet - all the complexity of communication between different languages and environments is handled for you by gRPC. We also get all the advantages of working with protocol buffers, including efficient serialization, a simple IDL, and easy interface updating.
-
-## Example code and setup
-
-The example code for our tutorial is in [grpc/grpc-go/examples/route_guide](https://github.com/grpc/grpc-go/tree/master/examples/route_guide). To download the example, clone the `grpc-go` repository by running the following command:
-```shell
-$ go get google.golang.org/grpc
-```
-
-Then change your current directory to `grpc-go/examples/route_guide`:
-```shell
-$ cd $GOPATH/src/google.golang.org/grpc/examples/route_guide
-```
-
-You also should have the relevant tools installed to generate the server and client interface code - if you don't already, follow the setup instructions in [the Go quick start guide](https://github.com/grpc/grpc-common/tree/master/go).
-
-
-## Defining the service
-
-Our first step (as you'll know from [Getting started](https://github.com/grpc/grpc-common)) is to define the gRPC *service* and the method *request* and *response* types using [protocol buffers] (https://developers.google.com/protocol-buffers/docs/overview). You can see the complete .proto file in [`grpc-common/protos/route_guide.proto`](https://github.com/grpc/grpc-common/blob/master/protos/route_guide.proto).
-
-To define a service, you specify a named `service` in your .proto file:
-
-```proto
-service RouteGuide {
- ...
-}
-```
-
-Then you define `rpc` methods inside your service definition, specifying their request and response types. gRPC lets you define four kinds of service method, all of which are used in the `RouteGuide` service:
-
-- A *simple RPC* where the client sends a request to the server using the stub and waits for a response to come back, just like a normal function call.
-```proto
- // Obtains the feature at a given position.
- rpc GetFeature(Point) returns (Feature) {}
-```
-
-- A *server-side streaming RPC* where the client sends a request to the server and gets a stream to read a sequence of messages back. The client reads from the returned stream until there are no more messages. As you can see in our example, you specify a server-side streaming method by placing the `stream` keyword before the *response* type.
-```proto
- // Obtains the Features available within the given Rectangle. Results are
- // streamed rather than returned at once (e.g. in a response message with a
- // repeated field), as the rectangle may cover a large area and contain a
- // huge number of features.
- rpc ListFeatures(Rectangle) returns (stream Feature) {}
-```
-
-- A *client-side streaming RPC* where the client writes a sequence of messages and sends them to the server, again using a provided stream. Once the client has finished writing the messages, it waits for the server to read them all and return its response. You specify a client-side streaming method by placing the `stream` keyword before the *request* type.
-```proto
- // Accepts a stream of Points on a route being traversed, returning a
- // RouteSummary when traversal is completed.
- rpc RecordRoute(stream Point) returns (RouteSummary) {}
-```
-
-- A *bidirectional streaming RPC* where both sides send a sequence of messages using a read-write stream. The two streams operate independently, so clients and servers can read and write in whatever order they like: for example, the server could wait to receive all the client messages before writing its responses, or it could alternately read a message then write a message, or some other combination of reads and writes. The order of messages in each stream is preserved. You specify this type of method by placing the `stream` keyword before both the request and the response.
-```proto
- // Accepts a stream of RouteNotes sent while a route is being traversed,
- // while receiving other RouteNotes (e.g. from other users).
- rpc RouteChat(stream RouteNote) returns (stream RouteNote) {}
-```
-
-Our .proto file also contains protocol buffer message type definitions for all the request and response types used in our service methods - for example, here's the `Point` message type:
-```proto
-// Points are represented as latitude-longitude pairs in the E7 representation
-// (degrees multiplied by 10**7 and rounded to the nearest integer).
-// Latitudes should be in the range +/- 90 degrees and longitude should be in
-// the range +/- 180 degrees (inclusive).
-message Point {
- int32 latitude = 1;
- int32 longitude = 2;
-}
-```
-
-
-## Generating client and server code
-
-Next we need to generate the gRPC client and server interfaces from our .proto service definition. We do this using the protocol buffer compiler `protoc` with a special gRPC Go plugin.
-
-For simplicity, we've provided a [bash script](https://github.com/grpc/grpc-go/blob/master/codegen.sh) that runs `protoc` for you with the appropriate plugin, input, and output (if you want to run this by yourself, make sure you've installed protoc and followed the gRPC-Go [installation instructions](https://github.com/grpc/grpc-go/blob/master/README.md) first):
-
-```shell
-$ codegen.sh route_guide.proto
-```
-
-which actually runs:
-
-```shell
-$ protoc --go_out=plugins=grpc:. route_guide.proto
-```
-
-Running this command generates the following file in your current directory:
-- `route_guide.pb.go`
-
-This contains:
-- All the protocol buffer code to populate, serialize, and retrieve our request and response message types
-- An interface type (or *stub*) for clients to call with the methods defined in the `RouteGuide` service.
-- An interface type for servers to implement, also with the methods defined in the `RouteGuide` service.
-
-
-
-## Creating the server
-
-First let's look at how we create a `RouteGuide` server. If you're only interested in creating gRPC clients, you can skip this section and go straight to [Creating the client](#client) (though you might find it interesting anyway!).
-
-There are two parts to making our `RouteGuide` service do its job:
-- Implementing the service interface generated from our service definition: doing the actual "work" of our service.
-- Running a gRPC server to listen for requests from clients and dispatch them to the right service implementation.
-
-You can find our example `RouteGuide` server in [grpc-go/examples/route_guide/server/server.go](https://github.com/grpc/grpc-go/tree/master/examples/route_guide/server/server.go). Let's take a closer look at how it works.
-
-### Implementing RouteGuide
-
-As you can see, our server has a `routeGuideServer` struct type that implements the generated `RouteGuideServer` interface:
-
-```go
-type routeGuideServer struct {
- ...
-}
-...
-
-func (s *routeGuideServer) GetFeature(ctx context.Context, point *pb.Point) (*pb.Feature, error) {
- ...
-}
-...
-
-func (s *routeGuideServer) ListFeatures(rect *pb.Rectangle, stream pb.RouteGuide_ListFeaturesServer) error {
- ...
-}
-...
-
-func (s *routeGuideServer) RecordRoute(stream pb.RouteGuide_RecordRouteServer) error {
- ...
-}
-...
-
-func (s *routeGuideServer) RouteChat(stream pb.RouteGuide_RouteChatServer) error {
- ...
-}
-...
-```
-
-#### Simple RPC
-`routeGuideServer` implements all our service methods. Let's look at the simplest type first, `GetFeature`, which just gets a `Point` from the client and returns the corresponding feature information from its database in a `Feature`.
-
-```go
-func (s *routeGuideServer) GetFeature(ctx context.Context, point *pb.Point) (*pb.Feature, error) {
- for _, feature := range s.savedFeatures {
- if proto.Equal(feature.Location, point) {
- return feature, nil
- }
- }
- // No feature was found, return an unnamed feature
- return &pb.Feature{"", point}, nil
-}
-```
-
-The method is passed a context object for the RPC and the client's `Point` protocol buffer request. It returns a `Feature` protocol buffer object with the response information and an `error`. In the method we populate the `Feature` with the appropriate information, and then `return` it along with an `nil` error to tell gRPC that we've finished dealing with the RPC and that the `Feature` can be returned to the client.
-
-#### Server-side streaming RPC
-Now let's look at one of our streaming RPCs. `ListFeatures` is a server-side streaming RPC, so we need to send back multiple `Feature`s to our client.
-
-```go
-func (s *routeGuideServer) ListFeatures(rect *pb.Rectangle, stream pb.RouteGuide_ListFeaturesServer) error {
- for _, feature := range s.savedFeatures {
- if inRange(feature.Location, rect) {
- if err := stream.Send(feature); err != nil {
- return err
- }
- }
- }
- return nil
-}
-```
-
-As you can see, instead of getting simple request and response objects in our method parameters, this time we get a request object (the `Rectangle` in which our client wants to find `Feature`s) and a special `RouteGuide_ListFeaturesServer` object to write our responses.
-
-In the method, we populate as many `Feature` objects as we need to return, writing them to the `RouteGuide_ListFeaturesServer` using its `Send()` method. Finally, as in our simple RPC, we return a `nil` error to tell gRPC that we've finished writing responses. Should any error happen in this call, we return a non-`nil` error; the gRPC layer will translate it into an appropriate RPC status to be sent on the wire.
-
-#### Client-side streaming RPC
-Now let's look at something a little more complicated: the client-side streaming method `RecordRoute`, where we get a stream of `Point`s from the client and return a single `RouteSummary` with information about their trip. As you can see, this time the method doesn't have a request parameter at all. Instead, it gets a `RouteGuide_RecordRouteServer` stream, which the server can use to both read *and* write messages - it can receive client messages using its `Recv()` method and return its single response using its `SendAndClose()` method.
-
-```go
-func (s *routeGuideServer) RecordRoute(stream pb.RouteGuide_RecordRouteServer) error {
- var pointCount, featureCount, distance int32
- var lastPoint *pb.Point
- startTime := time.Now()
- for {
- point, err := stream.Recv()
- if err == io.EOF {
- endTime := time.Now()
- return stream.SendAndClose(&pb.RouteSummary{
- PointCount: pointCount,
- FeatureCount: featureCount,
- Distance: distance,
- ElapsedTime: int32(endTime.Sub(startTime).Seconds()),
- })
- }
- if err != nil {
- return err
- }
- pointCount++
- for _, feature := range s.savedFeatures {
- if proto.Equal(feature.Location, point) {
- featureCount++
- }
- }
- if lastPoint != nil {
- distance += calcDistance(lastPoint, point)
- }
- lastPoint = point
- }
-}
-```
-
-In the method body we use the `RouteGuide_RecordRouteServer`s `Recv()` method to repeatedly read in our client's requests to a request object (in this case a `Point`) until there are no more messages: the server needs to check the the error returned from `Read()` after each call. If this is `nil`, the stream is still good and it can continue reading; if it's `io.EOF` the message stream has ended and the server can return its `RouteSummary`. If it has any other value, we return the error "as is" so that it'll be translated to an RPC status by the gRPC layer.
-
-#### Bidirectional streaming RPC
-Finally, let's look at our bidirectional streaming RPC `RouteChat()`.
-
-```go
-func (s *routeGuideServer) RouteChat(stream pb.RouteGuide_RouteChatServer) error {
- for {
- in, err := stream.Recv()
- if err == io.EOF {
- return nil
- }
- if err != nil {
- return err
- }
- key := serialize(in.Location)
- ... // look for notes to be sent to client
- for _, note := range s.routeNotes[key] {
- if err := stream.Send(note); err != nil {
- return err
- }
- }
- }
-}
-```
-
-This time we get a `RouteGuide_RouteChatServer` stream that, as in our client-side streaming example, can be used to read and write messages. However, this time we return values via our method's stream while the client is still writing messages to *their* message stream.
-
-The syntax for reading and writing here is very similar to our client-streaming method, except the server uses the stream's `Send()` method rather than `SendAndClose()` because it's writing multiple responses. Although each side will always get the other's messages in the order they were written, both the client and server can read and write in any order — the streams operate completely independently.
-
-### Starting the server
-
-Once we've implemented all our methods, we also need to start up a gRPC server so that clients can actually use our service. The following snippet shows how we do this for our `RouteGuide` service:
-
-```go
-flag.Parse()
-lis, err := net.Listen("tcp", fmt.Sprintf(":%d", *port))
-if err != nil {
- log.Fatalf("failed to listen: %v", err)
-}
-grpcServer := grpc.NewServer()
-pb.RegisterRouteGuideServer(grpcServer, &routeGuideServer{})
-... // determine whether to use TLS
-grpcServer.Serve(lis)
-```
-To build and start a server, we:
-
-1. Specify the port we want to use to listen for client requests using `lis, err := net.Listen("tcp", fmt.Sprintf(":%d", *port))`.
-2. Create an instance of the gRPC server using `grpc.NewServer()`.
-3. Register our service implementation with the gRPC server.
-4. Call `Serve()` on the server with our port details to do a blocking wait until the process is killed or `Stop()` is called.
-
-
-## Creating the client
-
-In this section, we'll look at creating a Go client for our `RouteGuide` service. You can see our complete example client code in [grpc-go/examples/route_guide/client/client.go](https://github.com/grpc/grpc-go/tree/master/examples/route_guide/client/client.go).
-
-### Creating a stub
-
-To call service methods, we first need to create a gRPC *channel* to communicate with the server. We create this by passing the server address and port number to `grpc.Dial()` as follows:
-
-```go
-conn, err := grpc.Dial(*serverAddr)
-if err != nil {
- ...
-}
-defer conn.Close()
-```
-
-You can use `DialOptions` to set the auth credentials (e.g., TLS, GCE credentials, JWT credentials) in `grpc.Dial` if the service you request requires that - however, we don't need to do this for our `RouteGuide` service.
-
-Once the gRPC *channel* is setup, we need a client *stub* to perform RPCs. We get this using the `NewRouteGuideClient` method provided in the `pb` package we generated from our .proto.
-
-```go
-client := pb.NewRouteGuideClient(conn)
-```
-
-### Calling service methods
-
-Now let's look at how we call our service methods. Note that in gRPC-Go, RPCs operate in a blocking/synchronous mode, which means that the RPC call waits for the server to respond, and will either return a response or an error.
-
-#### Simple RPC
-
-Calling the simple RPC `GetFeature` is nearly as straightforward as calling a local method.
-
-```go
-feature, err := client.GetFeature(context.Background(), &pb.Point{409146138, -746188906})
-if err != nil {
- ...
-}
-```
-
-As you can see, we call the method on the stub we got earlier. In our method parameters we create and populate a request protocol buffer object (in our case `Point`). We also pass a `context.Context` object which lets us change our RPC's behaviour if necessary, such as time-out/cancel an RPC in flight. If the call doesn't return an error, then we can read the response information from the server from the first return value.
-
-```go
-log.Println(feature)
-```
-
-#### Server-side streaming RPC
-
-Here's where we call the server-side streaming method `ListFeatures`, which returns a stream of geographical `Feature`s. If you've already read [Creating the server](#server) some of this may look very familiar - streaming RPCs are implemented in a similar way on both sides.
-
-```go
-rect := &pb.Rectangle{ ... } // initialize a pb.Rectangle
-stream, err := client.ListFeatures(context.Background(), rect)
-if err != nil {
- ...
-}
-for {
- feature, err := stream.Recv()
- if err == io.EOF {
- break
- }
- if err != nil {
- log.Fatalf("%v.ListFeatures(_) = _, %v", client, err)
- }
- log.Println(feature)
-}
-```
-
-As in the simple RPC, we pass the method a context and a request. However, instead of getting a response object back, we get back an instance of `RouteGuide_ListFeaturesClient`. The client can use the `RouteGuide_ListFeaturesClient` stream to read the server's responses.
-
-We use the `RouteGuide_ListFeaturesClient`'s `Recv()` method to repeatedly read in the server's responses to a response protocol buffer object (in this case a `Feature`) until there are no more messages: the client needs to check the error `err` returned from `Recv()` after each call. If `nil`, the stream is still good and it can continue reading; if it's `io.EOF` then the message stream has ended; otherwise there must be an RPC error, which is passed over through `err`.
-
-#### Client-side streaming RPC
-
-The client-side streaming method `RecordRoute` is similar to the server-side method, except that we only pass the method a context and get a `RouteGuide_RecordRouteClient` stream back, which we can use to both write *and* read messages.
-
-```go
-// Create a random number of random points
-r := rand.New(rand.NewSource(time.Now().UnixNano()))
-pointCount := int(r.Int31n(100)) + 2 // Traverse at least two points
-var points []*pb.Point
-for i := 0; i < pointCount; i++ {
- points = append(points, randomPoint(r))
-}
-log.Printf("Traversing %d points.", len(points))
-stream, err := client.RecordRoute(context.Background())
-if err != nil {
- log.Fatalf("%v.RecordRoute(_) = _, %v", client, err)
-}
-for _, point := range points {
- if err := stream.Send(point); err != nil {
- log.Fatalf("%v.Send(%v) = %v", stream, point, err)
- }
-}
-reply, err := stream.CloseAndRecv()
-if err != nil {
- log.Fatalf("%v.CloseAndRecv() got error %v, want %v", stream, err, nil)
-}
-log.Printf("Route summary: %v", reply)
-```
-
-The `RouteGuide_RecordRouteClient` has a `Send()` method that we can use to send requests to the server. Once we've finished writing our client's requests to the stream using `Send()`, we need to call `CloseAndRecv()` on the stream to let gRPC know that we've finished writing and are expecting to receive a response. We get our RPC status from the `err` returned from `CloseAndRecv()`. If the status is `nil`, then the first return value from `CloseAndRecv()` will be a valid server response.
-
-#### Bidirectional streaming RPC
-
-Finally, let's look at our bidirectional streaming RPC `RouteChat()`. As in the case of `RecordRoute`, we only pass the method a context object and get back a stream that we can use to both write and read messages. However, this time we return values via our method's stream while the server is still writing messages to *their* message stream.
-
-```go
-stream, err := client.RouteChat(context.Background())
-waitc := make(chan struct{})
-go func() {
- for {
- in, err := stream.Recv()
- if err == io.EOF {
- // read done.
- close(waitc)
- return
- }
- if err != nil {
- log.Fatalf("Failed to receive a note : %v", err)
- }
- log.Printf("Got message %s at point(%d, %d)", in.Message, in.Location.Latitude, in.Location.Longitude)
- }
-}()
-for _, note := range notes {
- if err := stream.Send(note); err != nil {
- log.Fatalf("Failed to send a note: %v", err)
- }
-}
-stream.CloseSend()
-<-waitc
-```
-
-The syntax for reading and writing here is very similar to our client-side streaming method, except we use the stream's `CloseSend()` method once we've finished our call. Although each side will always get the other's messages in the order they were written, both the client and server can read and write in any order — the streams operate completely independently.
-
-## Try it out!
-
-To compile and run the server, assuming you are in the folder
-`$GOPATH/src/google.golang.org/grpc/examples/route_guide`, simply:
-
-```sh
-$ go run server/server.go
-```
-
-Likewise, to run the client:
-
-```sh
-$ go run client/client.go
-```

-gRPC Hello World Tutorial (Android Java)
-========================
-
-BACKGROUND
--------------
-For this sample, we've already generated the server and client stubs from [helloworld.proto](https://github.com/grpc/grpc-common/blob/master/protos/helloworld.proto).
-
-PREREQUISITES
--------------
-- [Java gRPC](https://github.com/grpc/grpc-java)
-
-- [Android Tutorial](https://developer.android.com/training/basics/firstapp/index.html) if you're new to Android development

-#gRPC Basics: Java
-
-This tutorial provides a basic Java programmer's introduction to working with gRPC. By walking through this example you'll learn how to:
-
-- Define a service in a .proto file.
-- Generate server and client code using the protocol buffer compiler.
-- Use the Java gRPC API to write a simple client and server for your service.
-
-It assumes that you have read the [Getting started](https://github.com/grpc/grpc-common) guide and are familiar with [protocol buffers] (https://developers.google.com/protocol-buffers/docs/overview). Note that the example in this tutorial uses the [proto3](https://github.com/google/protobuf/releases) version of the protocol buffers language, which is currently in alpha release: you can find out more in the [proto3 language guide](https://developers.google.com/protocol-buffers/docs/proto3) and see the [release notes](https://github.com/google/protobuf/releases) for the new version in the protocol buffers Github repository.
-
-This isn't a comprehensive guide to using gRPC in Java: more reference documentation is coming soon.
-
-## Why use gRPC?
-
-Our example is a simple route mapping application that lets clients get information about features on their route, create a summary of their route, and exchange route information such as traffic updates with the server and other clients.
-
-With gRPC we can define our service once in a .proto file and implement clients and servers in any of gRPC's supported languages, which in turn can be run in environments ranging from servers inside Google to your own tablet - all the complexity of communication between different languages and environments is handled for you by gRPC. We also get all the advantages of working with protocol buffers, including efficient serialization, a simple IDL, and easy interface updating.
-
-## Example code and setup
-
-The example code for our tutorial is in [grpc/grpc-java/examples/src/main/java/io/grpc/examples](https://github.com/grpc/grpc-java/tree/master/examples/src/main/java/io/grpc/examples). To download the example, clone the `grpc-java` repository by running the following command:
-```shell
-$ git clone https://github.com/grpc/grpc-java.git
-```
-
-Then change your current directory to `grpc-java/examples`:
-```shell
-$ cd grpc-java/examples
-```
-
-You also should have the relevant tools installed to generate the server and client interface code - if you don't already, follow the setup instructions in [the Java quick start guide](https://github.com/grpc/grpc-common/tree/master/java).
-
-
-## Defining the service
-
-Our first step (as you'll know from [Getting started](https://github.com/grpc/grpc-common)) is to define the gRPC *service* and the method *request* and *response* types using [protocol buffers] (https://developers.google.com/protocol-buffers/docs/overview). You can see the complete .proto file in [`grpc-java/examples/src/main/proto/route_guide.proto`](https://github.com/grpc/grpc-java/blob/master/examples/src/main/proto/route_guide.proto).
-
-As we're generating Java code in this example, we've specified a `java_package` file option in our .proto:
-```proto
-option java_package = "io.grpc.examples";
-```
-
-This specifies the package we want to use for our generated Java classes. If no explicit `java_package` option is given in the .proto file, then by default the proto package (specified using the "package" keyword) will be used. However, proto packages generally do not make good Java packages since proto packages are not expected to start with reverse domain names. If we generate code in another language from this .proto, the `java_package` option has no effect.
-
-To define a service, we specify a named `service` in the .proto file:
-
-```proto
-service RouteGuide {
- ...
-}
-```
-
-Then we define `rpc` methods inside our service definition, specifying their request and response types. gRPC lets you define four kinds of service method, all of which are used in the `RouteGuide` service:
-
-- A *simple RPC* where the client sends a request to the server using the stub and waits for a response to come back, just like a normal function call.
-```proto
- // Obtains the feature at a given position.
- rpc GetFeature(Point) returns (Feature) {}
-```
-
-- A *server-side streaming RPC* where the client sends a request to the server and gets a stream to read a sequence of messages back. The client reads from the returned stream until there are no more messages. As you can see in our example, you specify a server-side streaming method by placing the `stream` keyword before the *response* type.
-```proto
- // Obtains the Features available within the given Rectangle. Results are
- // streamed rather than returned at once (e.g. in a response message with a
- // repeated field), as the rectangle may cover a large area and contain a
- // huge number of features.
- rpc ListFeatures(Rectangle) returns (stream Feature) {}
-```
-
-- A *client-side streaming RPC* where the client writes a sequence of messages and sends them to the server, again using a provided stream. Once the client has finished writing the messages, it waits for the server to read them all and return its response. You specify a server-side streaming method by placing the `stream` keyword before the *request* type.
-```proto
- // Accepts a stream of Points on a route being traversed, returning a
- // RouteSummary when traversal is completed.
- rpc RecordRoute(stream Point) returns (RouteSummary) {}
-```
-
-- A *bidirectional streaming RPC* where both sides send a sequence of messages using a read-write stream. The two streams operate independently, so clients and servers can read and write in whatever order they like: for example, the server could wait to receive all the client messages before writing its responses, or it could alternately read a message then write a message, or some other combination of reads and writes. The order of messages in each stream is preserved. You specify this type of method by placing the `stream` keyword before both the request and the response.
-```proto
- // Accepts a stream of RouteNotes sent while a route is being traversed,
- // while receiving other RouteNotes (e.g. from other users).
- rpc RouteChat(stream RouteNote) returns (stream RouteNote) {}
-```
-
-Our .proto file also contains protocol buffer message type definitions for all the request and response types used in our service methods - for example, here's the `Point` message type:
-```proto
-// Points are represented as latitude-longitude pairs in the E7 representation
-// (degrees multiplied by 10**7 and rounded to the nearest integer).
-// Latitudes should be in the range +/- 90 degrees and longitude should be in
-// the range +/- 180 degrees (inclusive).
-message Point {
- int32 latitude = 1;
- int32 longitude = 2;
-}
-```
-
-
-## Generating client and server code
-
-Next we need to generate the gRPC client and server interfaces from our .proto service definition. We do this using the protocol buffer compiler `protoc` with a special gRPC Java plugin. You need to use the [proto3](https://github.com/google/protobuf/releases) compiler in order to generate gRPC services
-
-For simplicity, we've provided a [Gradle build file](https://github.com/grpc/grpc-java/blob/master/examples/build.gradle) that runs `protoc` for you with the appropriate plugin, input, and output (if you want to run this yourself, make sure you've installed protoc and followed the gRPC code [installation instructions](https://github.com/grpc/grpc-java) first):
-
-```shell
-../gradlew build
-```
-
-which actually runs:
-
-```shell
-protoc -I examples/src/main/proto -I examples/build/extracted-protos/main --java_out=examples/build/generated-sources/main --java_plugin_out=examples/build/generated-sources/main --plugin=protoc-gen-java_plugin=compiler/build/binaries/java_pluginExecutable/java_plugin examples/src/main/proto/route_guide.proto
-```
-
-Running this command generates the following files:
-- `RouteGuideOuterClass.java`, which contains all the protocol buffer code to populate, serialize, and retrieve our request and response message types
-- `RouteGuideGrpc.java` which contains (along with some other useful code):
- - an interface for `RouteGuide` servers to implement, `RouteGuideGrpc.Service`, with all the methods defined in the `RouteGuide` service.
- - *stub* classes that clients can use to talk to a `RouteGuide` server. These also implement the `RouteGuide` interface.
-
-
-
-## Creating the server
-
-First let's look at how we create a `RouteGuide` server. If you're only interested in creating gRPC clients, you can skip this section and go straight to [Creating the client](#client) (though you might find it interesting anyway!).
-
-There are two parts to making our `RouteGuide` service do its job:
-- Implementing the service interface generated from our service definition: doing the actual "work" of our service.
-- Running a gRPC server to listen for requests from clients and return the service responses.
-
-You can find our example `RouteGuide` server in [grpc-java/examples/src/main/java/io/grpc/examples/RouteGuideServer.java](https://github.com/grpc/grpc-java/blob/master/examples/src/main/java/io/grpc/examples/RouteGuideServer.java). Let's take a closer look at how it works.
-
-### Implementing RouteGuide
-
-As you can see, our server has a `RouteGuideService` class that implements the generated `RouteGuideGrpc.Service` interface:
-
-```java
-private static class RouteGuideService implements RouteGuideGrpc.RouteGuide {
-...
-}
-```
-#### Simple RPC
-`RouteGuideService` implements all our service methods. Let's look at the simplest type first, `GetFeature`, which just gets a `Point` from the client and returns the corresponding feature information from its database in a `Feature`.
-
-```java
- @Override
- public void getFeature(Point request, StreamObserver responseObserver) {
- responseObserver.onValue(getFeature(request));
- responseObserver.onCompleted();
- }
-
-...
-
- private Feature getFeature(Point location) {
- for (Feature feature : features) {
- if (feature.getLocation().getLatitude() == location.getLatitude()
- && feature.getLocation().getLongitude() == location.getLongitude()) {
- return feature;
- }
- }
-
- // No feature was found, return an unnamed feature.
- return Feature.newBuilder().setName("").setLocation(location).build();
- }
-```
-
-`getFeature()` takes two parameters:
-- `Point`: the request
-- `StreamObserver`: a response observer, which is a special interface for the server to call with its response.
-
-To return our response to the client and complete the call:
-
-1. We construct and populate a `Feature` response object to return to the client, as specified in our service definition. In this example, we do this in a separate private `getFeature()` method.
-2. We use the response observer's `onValue()` method to return the `Feature`.
-3. We use the response observer's `onCompleted()` method to specify that we've finished dealing with the RPC.
-
-#### Server-side streaming RPC
-Next let's look at one of our streaming RPCs. `ListFeatures` is a server-side streaming RPC, so we need to send back multiple `Feature`s to our client.
-
-```java
-private final Collection features;
-
-...
-
- @Override
- public void listFeatures(Rectangle request, StreamObserver responseObserver) {
- int left = min(request.getLo().getLongitude(), request.getHi().getLongitude());
- int right = max(request.getLo().getLongitude(), request.getHi().getLongitude());
- int top = max(request.getLo().getLatitude(), request.getHi().getLatitude());
- int bottom = min(request.getLo().getLatitude(), request.getHi().getLatitude());
-
- for (Feature feature : features) {
- if (!RouteGuideUtil.exists(feature)) {
- continue;
- }
-
- int lat = feature.getLocation().getLatitude();
- int lon = feature.getLocation().getLongitude();
- if (lon >= left && lon <= right && lat >= bottom && lat <= top) {
- responseObserver.onValue(feature);
- }
- }
- responseObserver.onCompleted();
- }
-```
-
-Like the simple RPC, this method gets a request object (the `Rectangle` in which our client wants to find `Feature`s) and a `StreamObserver` response observer.
-
-This time, we get as many `Feature` objects as we need to return to the client (in this case, we select them from the service's feature collection based on whether they're inside our request `Rectangle`), and write them each in turn to the response observer using its `Write()` method. Finally, as in our simple RPC, we use the response observer's `onCompleted()` method to tell gRPC that we've finished writing responses.
-
-#### Client-side streaming RPC
-Now let's look at something a little more complicated: the client-side streaming method `RecordRoute`, where we get a stream of `Point`s from the client and return a single `RouteSummary` with information about their trip.
-
-```java
- @Override
- public StreamObserver recordRoute(final StreamObserver responseObserver) {
- return new StreamObserver() {
- int pointCount;
- int featureCount;
- int distance;
- Point previous;
- long startTime = System.nanoTime();
-
- @Override
- public void onValue(Point point) {
- pointCount++;
- if (RouteGuideUtil.exists(getFeature(point))) {
- featureCount++;
- }
- // For each point after the first, add the incremental distance from the previous point to
- // the total distance value.
- if (previous != null) {
- distance += calcDistance(previous, point);
- }
- previous = point;
- }
-
- @Override
- public void onError(Throwable t) {
- logger.log(Level.WARNING, "Encountered error in recordRoute", t);
- }
-
- @Override
- public void onCompleted() {
- long seconds = NANOSECONDS.toSeconds(System.nanoTime() - startTime);
- responseObserver.onValue(RouteSummary.newBuilder().setPointCount(pointCount)
- .setFeatureCount(featureCount).setDistance(distance)
- .setElapsedTime((int) seconds).build());
- responseObserver.onCompleted();
- }
- };
- }
-```
-
-As you can see, like the previous method types our method gets a `StreamObserver` response observer parameter, but this time it returns a `StreamObserver` for the client to write its `Point`s.
-
-In the method body we instantiate an anonymous `StreamObserver` to return, in which we:
-- Override the `onValue()` method to get features and other information each time the client writes a `Point` to the message stream.
-- Override the `onCompleted()` method (called when the *client* has finished writing messages) to populate and build our `RouteSummary`. We then call our method's own response observer's `onValue()` with our `RouteSummary`, and then call its `onCompleted()` method to finish the call from the server side.
-
-#### Bidirectional streaming RPC
-Finally, let's look at our bidirectional streaming RPC `RouteChat()`.
-
-```cpp
- @Override
- public StreamObserver routeChat(final StreamObserver responseObserver) {
- return new StreamObserver() {
- @Override
- public void onValue(RouteNote note) {
- List notes = getOrCreateNotes(note.getLocation());
-
- // Respond with all previous notes at this location.
- for (RouteNote prevNote : notes.toArray(new RouteNote[0])) {
- responseObserver.onValue(prevNote);
- }
-
- // Now add the new note to the list
- notes.add(note);
- }
-
- @Override
- public void onError(Throwable t) {
- logger.log(Level.WARNING, "Encountered error in routeChat", t);
- }
-
- @Override
- public void onCompleted() {
- responseObserver.onCompleted();
- }
- };
- }
-```
-
-As with our client-side streaming example, we both get and return a `StreamObserver` response observer, except this time we return values via our method's response observer while the client is still writing messages to *their* message stream. The syntax for reading and writing here is exactly the same as for our client-streaming and server-streaming methods. Although each side will always get the other's messages in the order they were written, both the client and server can read and write in any order — the streams operate completely independently.
-
-### Starting the server
-
-Once we've implemented all our methods, we also need to start up a gRPC server so that clients can actually use our service. The following snippet shows how we do this for our `RouteGuide` service:
-
-```java
- public void start() {
- gRpcServer = NettyServerBuilder.forPort(port)
- .addService(RouteGuideGrpc.bindService(new RouteGuideService(features)))
- .build().start();
- logger.info("Server started, listening on " + port);
- ...
- }
-```
-As you can see, we build and start our server using a `NettyServerBuilder`. This is a builder for servers based on the [Netty](http://netty.io/) transport framework.
-
-To do this, we:
-
-1. Create an instance of our service implementation class `RouteGuideService` and pass it to the generated `RouteGuideGrpc` class's static `bindService()` method to get a service definition.
-3. Specify the address and port we want to use to listen for client requests using the builder's `forPort()` method.
-4. Register our service implementation with the builder by passing the service definition returned from `bindService()` to the builder's `addService()` method.
-5. Call `build()` and `start()` on the builder to create and start an RPC server for our service.
-
-
-## Creating the client
-
-In this section, we'll look at creating a Java client for our `RouteGuide` service. You can see our complete example client code in [grpc-java/examples/src/main/java/io/grpc/examples/RouteGuideClient.java](https://github.com/grpc/grpc-java/blob/master/examples/src/main/java/io/grpc/examples/RouteGuideClient.java).
-
-### Creating a stub
-
-To call service methods, we first need to create a *stub*, or rather, two stubs:
-- a *blocking/synchronous* stub: this means that the RPC call waits for the server to respond, and will either return a response or raise an exception.
-- a *non-blocking/asynchronous* stub that makes non-blocking calls to the server, where the response is returned asynchronously. You can make certain types of streaming call only using the asynchronous stub.
-
-First we need to create a gRPC *channel* for our stub, specifying the server address and port we want to connect to:
-
-```java
- channel = NettyChannelBuilder.forAddress(host, port)
- .negotiationType(NegotiationType.PLAINTEXT)
- .build();
-```
-
-As with our server, we're using the [Netty](http://netty.io/) transport framework, so we use a `NettyChannelBuilder`.
-
-Now we can use the channel to create our stubs using the `newStub` and `newBlockingStub` methods provided in the `RouteGuideGrpc` class we generated from our .proto.
-
-```java
- blockingStub = RouteGuideGrpc.newBlockingStub(channel);
- asyncStub = RouteGuideGrpc.newStub(channel);
-```
-
-### Calling service methods
-
-Now let's look at how we call our service methods.
-
-#### Simple RPC
-
-Calling the simple RPC `GetFeature` on the blocking stub is as straightforward as calling a local method.
-
-```java
- Point request = Point.newBuilder().setLatitude(lat).setLongitude(lon).build();
- Feature feature = blockingStub.getFeature(request);
-```
-
-We create and populate a request protocol buffer object (in our case `Point`), pass it to the `getFeature()` method on our blocking stub, and get back a `Feature`.
-
-#### Server-side streaming RPC
-
-Next, let's look at a server-side streaming call to `ListFeatures`, which returns a stream of geographical `Feature`s:
-
-```java
- Rectangle request =
- Rectangle.newBuilder()
- .setLo(Point.newBuilder().setLatitude(lowLat).setLongitude(lowLon).build())
- .setHi(Point.newBuilder().setLatitude(hiLat).setLongitude(hiLon).build()).build();
- Iterator features = blockingStub.listFeatures(request);
-```
-
-As you can see, it's very similar to the simple RPC we just looked at, except instead of returning a single `Feature`, the method returns an `Iterator` that the client can use to read all the returned `Feature`s.
-
-#### Client-side streaming RPC
-
-Now for something a little more complicated: the client-side streaming method `RecordRoute`, where we send a stream of `Point`s to the server and get back a single `RouteSummary`. For this method we need to use the asynchronous stub. If you've already read [Creating the server](#server) some of this may look very familiar - asynchronous streaming RPCs are implemented in a similar way on both sides.
-
-```java
- public void recordRoute(List features, int numPoints) throws Exception {
- info("*** RecordRoute");
- final SettableFuture finishFuture = SettableFuture.create();
- StreamObserver responseObserver = new StreamObserver() {
- @Override
- public void onValue(RouteSummary summary) {
- info("Finished trip with {0} points. Passed {1} features. "
- + "Travelled {2} meters. It took {3} seconds.", summary.getPointCount(),
- summary.getFeatureCount(), summary.getDistance(), summary.getElapsedTime());
- }
-
- @Override
- public void onError(Throwable t) {
- finishFuture.setException(t);
- }
-
- @Override
- public void onCompleted() {
- finishFuture.set(null);
- }
- };
-
- StreamObserver requestObserver = asyncStub.recordRoute(responseObserver);
- try {
- // Send numPoints points randomly selected from the features list.
- StringBuilder numMsg = new StringBuilder();
- Random rand = new Random();
- for (int i = 0; i < numPoints; ++i) {
- int index = rand.nextInt(features.size());
- Point point = features.get(index).getLocation();
- info("Visiting point {0}, {1}", RouteGuideUtil.getLatitude(point),
- RouteGuideUtil.getLongitude(point));
- requestObserver.onValue(point);
- // Sleep for a bit before sending the next one.
- Thread.sleep(rand.nextInt(1000) + 500);
- if (finishFuture.isDone()) {
- break;
- }
- }
- info(numMsg.toString());
- requestObserver.onCompleted();
-
- finishFuture.get();
- info("Finished RecordRoute");
- } catch (Exception e) {
- requestObserver.onError(e);
- logger.log(Level.WARNING, "RecordRoute Failed", e);
- throw e;
- }
- }
-```
-
-As you can see, to call this method we need to create a `StreamObserver`, which implements a special interface for the server to call with its `RouteSummary` response. In our `StreamObserver` we:
-- Override the `onValue()` method to print out the returned information when the server writes a `RouteSummary` to the message stream.
-- Override the `onCompleted()` method (called when the *server* has completed the call on its side) to set a `SettableFuture` that we can check to see if the server has finished writing.
-
-We then pass the `StreamObserver` to the asynchronous stub's `recordRoute()` method and get back our own `StreamObserver` request observer to write our `Point`s to send to the server. Once we've finished writing points, we use the request observer's `onCompleted()` method to tell gRPC that we've finished writing on the client side. Once we're done, we check our `SettableFuture` to check that the server has completed on its side.
-
-#### Bidirectional streaming RPC
-
-Finally, let's look at our bidirectional streaming RPC `RouteChat()`.
-
-```java
- public void routeChat() throws Exception {
- info("*** RoutChat");
- final SettableFuture finishFuture = SettableFuture.create();
- StreamObserver requestObserver =
- asyncStub.routeChat(new StreamObserver() {
- @Override
- public void onValue(RouteNote note) {
- info("Got message \"{0}\" at {1}, {2}", note.getMessage(), note.getLocation()
- .getLatitude(), note.getLocation().getLongitude());
- }
-
- @Override
- public void onError(Throwable t) {
- finishFuture.setException(t);
- }
-
- @Override
- public void onCompleted() {
- finishFuture.set(null);
- }
- });
-
- try {
- RouteNote[] requests =
- {newNote("First message", 0, 0), newNote("Second message", 0, 1),
- newNote("Third message", 1, 0), newNote("Fourth message", 1, 1)};
-
- for (RouteNote request : requests) {
- info("Sending message \"{0}\" at {1}, {2}", request.getMessage(), request.getLocation()
- .getLatitude(), request.getLocation().getLongitude());
- requestObserver.onValue(request);
- }
- requestObserver.onCompleted();
-
- finishFuture.get();
- info("Finished RouteChat");
- } catch (Exception t) {
- requestObserver.onError(t);
- logger.log(Level.WARNING, "RouteChat Failed", t);
- throw t;
- }
- }
-```
-
-As with our client-side streaming example, we both get and return a `StreamObserver` response observer, except this time we send values via our method's response observer while the server is still writing messages to *their* message stream. The syntax for reading and writing here is exactly the same as for our client-streaming method. Although each side will always get the other's messages in the order they were written, both the client and server can read and write in any order — the streams operate completely independently.
