Method Detail

oneway

public void oneway(Object command)
            throws IOException

Description copied from interface: Transport

A one way asynchronous send

Specified by:

oneway in interface Transport

Throws:

IOException

sendToActiveMQ

public void sendToActiveMQ(Command command)

Specified by:

sendToActiveMQ in interface StompTransport

doStop

protected void doStop(ServiceStopper stopper)
               throws Exception

Specified by:

doStop in class ServiceSupport

Throws:

Exception

doStart

protected void doStart()
                throws Exception

Specified by:

doStart in class ServiceSupport

Throws:

Exception

sendToStomp

public abstract void sendToStomp(StompFrame command)
                          throws IOException

Specified by:

sendToStomp in interface StompTransport

Throws:

IOException

handleStopped

public abstract void handleStopped()
                            throws IOException

Called when the transport is stopping to allow the dervied classes a chance to close WebSocket resources.

getInactivityMonitor

public StompInactivityMonitor getInactivityMonitor()

Specified by:

getInactivityMonitor in interface StompTransport

getWireFormat

public StompWireFormat getWireFormat()

Specified by:

getWireFormat in interface StompTransport

getRemoteAddress

public String getRemoteAddress()

Specified by:

getRemoteAddress in interface Transport

Returns:

the remote address for this connection

getReceiveCounter

public int getReceiveCounter()

Description copied from interface: Transport

Returns a counter which gets incremented as data is read from the transport. It should only be used to determine if there is progress being made in reading the next command from the transport. The value may wrap into the negative numbers.

Specified by:

getReceiveCounter in interface Transport

Returns:

a counter which gets incremented as data is read from the transport.

processStompFrame

protected void processStompFrame(String data)
