- * Interface for an RPC callback, normally called when an RPC completes.
- * {@code ParameterType} is normally the method's response message type.
- *
- * <p>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.
