Description copied from interface: ClientTransport

Creates a new stream for sending messages to a remote end-point.

This method returns immediately and does not wait for any validation of the request. If creation fails for any reason, ClientStreamListener.closed(io.grpc.Status, io.grpc.internal.ClientStreamListener.RpcProgress, io.grpc.Metadata) will be called to provide the error information. Any sent messages for this stream will be buffered until creation has completed (either successfully or unsuccessfully).

This method is called under the Context of the ClientCall.

Specified by:

newStream in interface ClientTransport

Overrides:

newStream in class ForwardingConnectionClientTransport

Parameters:

method - the descriptor of the remote method to be called for this stream.

headers - to send at the beginning of the call

callOptions - runtime options of the call

tracers - a non-empty array of tracers. The last element in it is reserved to be set by the load balancer's pick result and otherwise is a no-op tracer.

Returns:

the newly created stream.
