Method Detail

init

public void init()

Description copied from interface: HasLifecycle

Called from the enclosing Subsystem at initialization phase.

This method is called before the children components of this object have their init method called.

At the time it is called, connection to the messaging layer is not yet done, so there should be no attempt to send messages in the body of this method. Configuration for message listening can nevertheless be done here, such as adding MessageListener objects.

It is unnecessary to call super.init()

Specified by:

init in interface HasLifecycle

postInit

public void postInit()

Description copied from interface: HasLifecycle

Called from the enclosing Subsystem at construction phase. This method is called after init and postInit have been called on this component's children.

Specified by:

postInit in interface HasLifecycle
