Package akka.protobuf

Class GeneratedMessage.GeneratedExtension<ContainingType extends Message,Type>

java.lang.Object

akka.protobuf.GeneratedMessage.GeneratedExtension<ContainingType,Type>

Enclosing class:

GeneratedMessage

public static final class GeneratedMessage.GeneratedExtension<ContainingType extends Message,Type>
extends java.lang.Object

Type used to represent generated extensions. The protocol compiler generates a static singleton instance of this class for each extension.

For example, imagine you have the .proto file:

 option java_class = "MyProto";

 message Foo {
   extensions 1000 to max;
 }

 extend Foo {
   optional int32 bar;
 }
 

Then, MyProto.Foo.bar has type GeneratedExtension<MyProto.Foo, Integer>.

In general, users should ignore the details of this type, and simply use these static singletons as parameters to the extension accessors defined in GeneratedMessage.ExtendableMessage and GeneratedMessage.ExtendableBuilder.
