newStream

public ClientStream newStream(MethodDescriptor<?,?> method,
                              Metadata headers,
                              CallOptions callOptions,
                              ClientStreamTracer[] tracers)

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.

shutdown

public void shutdown(Status status)

Description copied from interface: ManagedClientTransport

Initiates an orderly shutdown of the transport. Existing streams continue, but the transport will not own any new streams. New streams will either fail (once ManagedClientTransport.Listener.transportShutdown(io.grpc.Status) callback called), or be transferred off this transport (in which case they may succeed). This method may only be called once.

Specified by:

shutdown in interface ManagedClientTransport

Overrides:

shutdown in class ForwardingConnectionClientTransport

shutdownNow

public void shutdownNow(Status status)

Description copied from interface: ManagedClientTransport

Initiates a forceful shutdown in which preexisting and new calls are closed. Existing calls should be closed with the provided reason.

Specified by:

shutdownNow in interface ManagedClientTransport

Overrides:

shutdownNow in class ForwardingConnectionClientTransport

maybeShutdown

private void maybeShutdown()
