All Implemented Interfaces:
org.refcodes.mixin.ActionAccessor<PropertyAction>, org.refcodes.mixin.KeyAccessor<String>, org.refcodes.mixin.SourceAccessor<ObservableProperties>, org.refcodes.mixin.ValueAccessor<String>, org.refcodes.observer.ActionEvent<PropertyAction,ObservableProperties>, org.refcodes.observer.Event<ObservableProperties>, org.refcodes.struct.Property, org.refcodes.struct.Relation<String,String>
public class 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 CanonicalMap.MutableCanonicalMap.put(Object, String) 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().
