Method Detail

preInit

public void preInit()

preStart

public void preStart()

Called from the enclosing Subsystem when HasLifecycle.start() has been called.

The preceding lifecycle step is HasLifecycle.postInit()

The following lifecycle step is HasLifecycle.start() At the time it is called :

• the PhaseState is INITIALIZING
• connection with the messaging layer is effective, the enclosing subsystem has started StatusHeartBeat publication

preStop

public void preStop()
