An RpcChannel represents a communication line to a service which can be used
91
to call that service's methods. The service may be running on another
92
machine. Normally, you should not use an RpcChannel directly, but instead
93
construct a stub {@link Service} wrapping it. Example:
96
RpcChannel channel = rpcImpl.Channel("remotehost.example.com:1234")

The primary purpose of the controller is to provide a way to manipulate
105
settings specific to the RPC implementation and to find out about RPC-level
106
errors. The methods provided by the RpcController interface are intended
107
to be a "least common denominator" set of features which we expect all
108
implementations to support. Specific implementations may provide more
109
advanced features (e.g. deadline propagation).
