public static final Object newValue
public static final Object oldValue
Map decorator that will trigger PropertyChangeEvents when a value changes.
An optional Closure may be specified and will work as a filter, if it returns true the property will trigger an event (if the value indeed changed), otherwise it won't. The Closure may receive 1 or 2 parameters, the single one being the value, the other one both the key and value, for example:
// skip all properties whose value is a closure
def map = new ObservableMap( {!(it instanceof Closure)} )
// skip all properties whose name matches a regex
def map = new ObservableMap( { name, value -> !(name =~ /[A-Z+]/) } )
The current implementation will trigger specialized events in the following scenarios, you need not register a different listener as those events extend from PropertyChangeEvent
- ObservableMap.PropertyAddedEvent - a new property is added to the map
- ObservableMap.PropertyRemovedEvent - a property is removed from the map
- ObservableMap.PropertyUpdatedEvent - a property changes value (same as regular PropertyChangeEvent)
- ObservableMap.PropertyClearedEvent - all properties have been removed from the map
- ObservableMap.MultiPropertyEvent - triggered by calling map.putAll(), contains Added|Updated events
