public abstract static class GeneratedMessageLite.ExtendableMessage<MessageType extends GeneratedMessageLite.ExtendableMessage<MessageType,BuilderType>,BuilderType extends GeneratedMessageLite.ExtendableBuilder<MessageType,BuilderType>> extends GeneratedMessageLite<MessageType,BuilderType> implements GeneratedMessageLite.ExtendableMessageOrBuilder<MessageType,BuilderType>
This class implements type-safe accessors for extensions. They implement all the same operations that you can do
with normal fields -- e.g. "has", "get", and "getCount" -- but for extensions. The extensions are identified
using instances of the class GeneratedMessageLite.GeneratedExtension; the protocol compiler generates a static instance of
this class for every extension in its input. Through the magic of generics, all is made type-safe.
For example, imagine you have the .proto file:
option java_class = "MyProto";
message Foo {
extensions 1000 to max;
}
extend Foo {
optional int32 bar;
}
Then you might write code like:
MyProto.Foo foo = getFoo(); int i = foo.getExtension(MyProto.bar);
