Class PropertyListenerDescriptor

java.lang.Object

com.inductiveautomation.factorypmi.application.binding.PropertyInteractionDescriptor

com.inductiveautomation.factorypmi.application.binding.PropertyListenerDescriptor

All Implemented Interfaces:

Adapter.ValueHolder, InteractionDescriptor, PropertyChangeListener, EventListener

public class PropertyListenerDescriptor
extends PropertyInteractionDescriptor
implements PropertyChangeListener, Adapter.ValueHolder

This subclass of PropertyInteractionDescriptor is simply an PID that is also the listener, and a ValueHolder. This means that this class directly listens to the source, and holds the value when the source value changes.
