Class AbstractConnectedMessageListener<CLNT extends AbstractStampyMessageGateway>

java.lang.Object

asia.stampy.client.listener.connected.AbstractConnectedMessageListener<CLNT>

All Implemented Interfaces:

StampyMessageListener

Direct Known Subclasses:

NettyConnectedMessageListener

@StampyLibrary(libraryName="stampy-client-server")
public abstract class AbstractConnectedMessageListener<CLNT extends AbstractStampyMessageGateway>
extends java.lang.Object
implements StampyMessageListener

This class intercepts incoming StompMessageType.CONNECTED from a STOMP 1.2 server and starts a heartbeat, if requested. CONNECT heart-beat:[cx],[cy]
CONNECTED: heart-beat:[sx],[sy]

For heart-beats from the client to the server: if [cx] is 0 (the client cannot send heart-beats) or [sy] is 0 (the server does not want to receive heart-beats) then there will be none otherwise, there will be heart-beats every MAX([cx],[sy]) milliseconds In the other direction, [sx] and [cy] are used the same way.
