Class GeneratedMessageLite.ExtendableMessage<MessageType extends GeneratedMessageLite.ExtendableMessage<MessageType,BuilderType>,BuilderType extends GeneratedMessageLite.ExtendableBuilder<MessageType,BuilderType>>

Enclosing class:

GeneratedMessageLite<MessageType extends GeneratedMessageLite<MessageType,BuilderType>,BuilderType extends GeneratedMessageLite.Builder<MessageType,BuilderType>>

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>

Generated message classes for message types that contain extension ranges subclass this.

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);
