Method Details

isListenerForSource

public boolean isListenerForSource(Object source)

Only listens on UIViewRoot.

Specified by:

isListenerForSource in interface SystemEventListener

processEvent

public void processEvent(SystemEvent event)

If the socket has just switched the connected attribute, then render either the open() script or the close() script. During an ajax request with partial rendering, it's added as <eval> by partial response writer, else it's just added as a script component with target="body". Those scripts will in turn hit SocketEndpoint.
