BidiStreamingCallable<RequestT
,
ResponseT
>
A BidiStreamingCallable is an immutable object which is capable of making RPC calls to bidirectional streaming API methods. Not all transports support streaming.
It is considered advanced usage for a user to create a BidiStreamingCallable 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.
