Method Detail

delegate

protected ClientCall.Listener<RespT> delegate()

Description copied from class: ForwardingClientCallListener

Returns the delegated ClientCall.Listener.

Specified by:

delegate in class ForwardingClientCallListener<RespT>

onHeaders

public void onHeaders(Metadata headers)

Description copied from class: ClientCall.Listener

The response headers have been received. Headers always precede messages.

Overrides:

onHeaders in class ClientCall.Listener<RespT>

Parameters:

headers - containing metadata sent by the server at the start of the response.

onClose

public void onClose(Status status,
                    Metadata trailers)

Description copied from class: ClientCall.Listener

The ClientCall has been closed. Any additional calls to the ClientCall will not be processed by the server. No further receiving will occur and no further notifications will be made.

If status returns false for Status.isOk(), then the call failed. An additional block of trailer metadata may be received at the end of the call from the server. An empty Metadata object is passed if no trailers are received.

Overrides:

onClose in class ClientCall.Listener<RespT>

Parameters:

status - the result of the remote call.

trailers - metadata provided at call completion.

onReady

public void onReady()

Description copied from class: ClientCall.Listener

This indicates that the ClientCall is now capable of sending additional messages (via ClientCall.sendMessage(ReqT)) without requiring excessive buffering internally. This event is just a suggestion and the application is free to ignore it, however doing so may result in excessive buffering within the ClientCall.

Overrides:

onReady in class ClientCall.Listener<RespT>
