Class Empty

public final class Empty extends GeneratedMessageLite<Empty,Empty.Builder> implements EmptyOrBuilder

A generic empty message that you can re-use to avoid defining duplicated empty messages in your APIs. A typical example is to use it as the request or the response type of an API method. For instance: service Foo { rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty); } The JSON representation for Empty is empty JSON object {}.

Protobuf type google.protobuf.Empty

Implements

Methods

dynamicMethod(GeneratedMessageLite.MethodToInvoke method, Object arg0, Object arg1)

protected final Object dynamicMethod(GeneratedMessageLite.MethodToInvoke method, Object arg0, Object arg1)

A method that implements different types of operations described in MethodToInvoke. These different kinds of operations are required to implement message-level operations for builders in the runtime. This method bundles those operations to reduce the generated methods count.

  • NEW_INSTANCE returns a new instance of the protocol buffer that has not yet been made immutable. See MAKE_IMMUTABLE.
  • IS_INITIALIZED returns null for false and the default instance for true. It doesn't use or modify any memoized value.
  • GET_MEMOIZED_IS_INITIALIZED returns the memoized isInitialized byte value.
  • SET_MEMOIZED_IS_INITIALIZED sets the memoized isInitialized byte value to 1 if the first parameter is not null, or to 0 if the first parameter is null.
  • NEW_BUILDER returns a BuilderType instance.

This method, plus the implementation of the Builder, enables the Builder class to be proguarded away entirely on Android.

For use by generated code only.
