|
* |
|
* package foo; |
|
* message Bar { |
|
* message Baz {} |
|
* } |
|

* The descriptor for this must look like this: |
|
* |
|
* file { |
|
* name: "test.proto" |
|
* package: "foo" |
|
* message_type { |
|
* name: "Bar" |
|
* nested_type { |
|
* name: "Baz" |
|
* } |

* } |

* non-nested way: |
|
* |
|
* Google::Protobuf::DescriptorPool.generated_pool.build do |
|
* add_message "foo.Bar" do |
|
* end |
|
* add_message "foo.Bar.Baz" do |
|
* end |
|
* end |
|
* |
|
* Here we need to do a translation where we turn this generated code into the |
|
* above descriptor. We need to infer that "foo" is the package name, and not |
|
* a message itself. |
|
* |
|
* We delegate to Ruby to compute the transformation, for more concice and |
