Interface PoshElementListener<PARENT extends PoshElement>

Type Parameters:

PARENT - Type of parent that the listeners will be notified about.

All Superinterfaces:

EventListener, PropertyChangeListener

All Known Implementing Classes:

LapChain

public interface PoshElementListener<PARENT extends PoshElement>
extends PropertyChangeListener

Mainly for widgets. This is the listener that can be registered with the PoshElement to listen for various events that happens to the POSH element (new node, deleted node...)

Thanks to generics, listeners can have type check for parent, but not for child because of multiple possible types of children (e.g. DC has two types of children, Sense and DriveElement, PoshPlan has ActionPattern and Competence).
