Examples of RpcController

com.google.protobuf.RpcController

An {@code RpcController} mediates a single method call. The primarypurpose of the controller is to provide a way to manipulate settings specific to the RPC implementation and to find out about RPC-level errors.
Starting with version 2.3.0, RPC implementations should not try to build on this, but should instead provide code generator plugins which generate code specific to the particular RPC implementation. This way the generated code can be more appropriate for the implementation in use and can avoid unnecessary layers of indirection.
The methods provided by the {@code RpcController} interface are intendedto be a "least common denominator" set of features which we expect all implementations to support. Specific implementations may provide more advanced features (e.g. deadline propagation). @author kenton@google.com Kenton Varda
