public WebSocketTransport(WebSocketClient webSocketClient)

Method Detail

getWebSocketClient

public WebSocketClient getWebSocketClient()

Return the configured WebSocketClient.

getTransportTypes

public java.util.List<TransportType> getTransportTypes()

Description copied from interface: Transport

Return the SockJS transport types that this transport can be used for. In particular since from a client perspective there is no difference between XHR and XHR streaming, an XhrTransport could do both.

Specified by:

getTransportTypes in interface Transport

connect

public ListenableFuture<WebSocketSession> connect(TransportRequest request,
                                                  WebSocketHandler handler)

Description copied from interface: Transport

Connect the transport.

Specified by:

connect in interface Transport

Parameters:

request - the transport request.

handler - the application handler to delegate lifecycle events to.

Returns:

a future to indicate success or failure to connect.

start

public void start()

Description copied from interface: Lifecycle

Start this component.

Should not throw an exception if the component is already running.

In the case of a container, this will propagate the start signal to all components that apply.

Specified by:

start in interface Lifecycle

See Also:

SmartLifecycle.isAutoStartup()

stop

public void stop()

Description copied from interface: Lifecycle

Stop this component, typically in a synchronous fashion, such that the component is fully stopped upon return of this method. Consider implementing SmartLifecycle and its stop(Runnable) variant when asynchronous stop behavior is necessary.

Note that this stop notification is not guaranteed to come before destruction: On regular shutdown, Lifecycle beans will first receive a stop notification before the general destruction callbacks are being propagated; however, on hot refresh during a context's lifetime or on aborted refresh attempts, only destroy methods will be called.

Should not throw an exception if the component isn't started yet.

In the case of a container, this will propagate the stop signal to all components that apply.

Specified by:

stop in interface Lifecycle

See Also:

SmartLifecycle.stop(Runnable), DisposableBean.destroy()

isRunning

public boolean isRunning()

Description copied from interface: Lifecycle

Check whether this component is currently running.

In the case of a container, this will return true only if all components that apply are currently running.

Specified by:

isRunning in interface Lifecycle

Returns:

whether the component is currently running

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
