@Generated(value="proto") public final class Empty extends GeneratedMessageV3 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
