Interface PropertyUpdatedEvent

All Superinterfaces:

org.refcodes.mixin.ActionAccessor<PropertyAction>, org.refcodes.observer.GenericActionEvent<PropertyAction,ObservableProperties>, org.refcodes.observer.GenericEvent<PropertyAction>, org.refcodes.mixin.KeyAccessor<PropertyAction>, org.refcodes.struct.Property, PropertyEvent, org.refcodes.struct.Relation<PropertyAction,ObservableProperties>, org.refcodes.mixin.SourceAccessor<PropertyAction>, org.refcodes.mixin.ValueAccessor<PropertyAction>

All Known Implementing Classes:

PropertyUpdatedEventImpl

public interface PropertyUpdatedEvent
extends PropertyEvent

The PropertyUpdatedEvent is fired whenever an existing property (as of Keys.containsKey(Object)) is updated in the related ObservableProperties instance (as of Keys.MutableValues.put(Object, Object) or the like). A PropertyUpdatedEvent represents a Property with a key and a value (as of KeyAccessor.getKey() and ValueAccessor.getValue()) of the updated property and the previous value of the property, accessible via getPreviousValue().
