Field Detail

• public static final Object newValue

• public static final Object oldValue

  Set 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 set = new ObservableSet( {!(it instanceof Closure)} )
   <p/>
   // skip all properties whose name matches a regex
   def set = new ObservableSet( { 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
  • ObservableSet.ElementAddedEvent - a new element is added to the set
  • ObservableSet.ElementRemovedEvent - an element is removed from the set
  • ObservableSet.ElementUpdatedEvent - an element changes value (same as regular PropertyChangeEvent)
  • ObservableSet.ElementClearedEvent - all elements have been removed from the list
  • ObservableSet.MultiElementAddedEvent - triggered by calling set.addAll()
  • ObservableSet.MultiElementRemovedEvent - triggered by calling set.removeAll()/set.retainAll()

  Bound properties

  • content - read-only.
  • size - read-only.
