Class ClientStreamingCallable<RequestT,ResponseT> (2.13.0) 

public abstract class ClientStreamingCallable<RequestT,ResponseT>

A ClientStreamingCallable is an immutable object which is capable of making RPC calls to client streaming API methods. Not all transports support streaming.

It is considered advanced usage for a user to create a ClientStreamingCallable themselves. This class is intended to be created by a generated client class, and configured by instances of StreamingCallSettings.Builder which are exposed through the client settings class.
