+/**
+ * Constructs a new Map. A Map is a container that is used to implement map
+ * fields on message objects. It closely follows the ES6 Map API; however,
+ * it is distinct because we do not want to depend on external polyfills or
+ * on ES6 itself.
+ *
+ * This constructor should only be called from generated message code. It is not
+ * intended for general use by library consumers. The callback function
+ * arguments are references to methods in `BinaryReader` and `BinaryWriter`, as
+ * well as constructors and reader/writer methods in submessage types if
+ * appropriate, that are used for binary serialization and parsing.
+ *
+ * @template K, V
+ *
+ * @param {!Array<!Array<!Object>>} arr
+ *
+ * @param {function(this:jspb.BinaryWriter,number,K)=} opt_keyWriterFn
+ *     The method on BinaryWriter that writes type K to the stream.
+ *
+ * @param {function(this:jspb.BinaryReader):K=} opt_keyReaderFn
+ *     The method on BinaryReader that reads type K from the stream.
+ *
+ * @param {function(this:jspb.BinaryWriter,number,V)|
+ *         function(this:jspb.BinaryReader,V,?)=} opt_valueWriterFn
+ *     The method on BinaryWriter that writes type V to the stream.  May be
+ *     writeMessage, in which case the second callback arg form is used.
+ *
+ * @param {function(this:jspb.BinaryReader):V|
+ *         function(this:jspb.BinaryReader,V,
+ *                  function(V,!jspb.BinaryReader))=} opt_valueReaderFn
+ *    The method on BinaryReader that reads type V from the stream. May be
+ *    readMessage, in which case the second callback arg form is used.
+ *
+ * @param {?function(new:V)|function(new:V,?)=} opt_valueCtor
+ *    The constructor for type V, if type V is a message type.
+ *
+ * @param {?function(V,!jspb.BinaryWriter)=} opt_valueWriterCallback
+ *    The BinaryWriter serialization callback for type V, if V is a message
+ *    type.

+ *    The BinaryReader parsing callback for type V, if V is a message type.
