@Generated(value="proto") public static class GeneratedMessage.GeneratedExtension<ContainingType extends Message,Type> extends Extension<ContainingType,Type>
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
.
