  • Constructor Details

    • BidiObservableMap

      public BidiObservableMap(IObservableMap<K,V> wrappedMap)
      Constructs a BidirectionalMap tracking the given observable map.
      Parameters:
      wrappedMap - the observable map to track

  • Method Details

    • firstListenerAdded

      protected void firstListenerAdded()
      Overrides:
      firstListenerAdded in class DecoratingObservableMap<K,V>

    • lastListenerRemoved

      protected void lastListenerRemoved()
      Overrides:
      lastListenerRemoved in class DecoratingObservableMap<K,V>

    • handleMapChange

      protected void handleMapChange(MapChangeEvent<? extends K,? extends V> event)
      Description copied from class: DecoratingObservableMap
      Called whenever a MapChangeEvent is received from the decorated observable. By default, this method fires the map change event again, with the decorating observable as the event source. Subclasses may override to provide different behavior.
      Overrides:
      handleMapChange in class DecoratingObservableMap<K,V>
      Parameters:
      event - the change event received from the decorated observable

    • containsValue

      public boolean containsValue(Object value)
      Specified by:
      containsValue in interface IObservableMap<K,V>
      Specified by:
      containsValue in interface Map<K,V>
      Overrides:
      containsValue in class DecoratingObservableMap<K,V>

    • getKeys

      public Set<K> getKeys(Object value)
      Returns the Set of keys that currently map to the given value.
      Parameters:
      value - the value associated with the keys in the returned Set.
      Returns:
      the Set of keys that map to the given value. If no keys map to the given value, an empty set is returned.

    • dispose

      public void dispose()
      Description copied from interface: IObservable
      Disposes of this observable object, removing all listeners registered with this object, and all listeners this object might have registered on other objects.
      Specified by:
      dispose in interface IObservable
      Overrides:
      dispose in class DecoratingObservableMap<K,V>

    • addListener

      protected void addListener(Object listenerType, IObservablesListener listener)
      Parameters:
      listenerType - arbitrary object to identify a type of the listener
      listener - the listener to add; not null

    • removeListener

      protected void removeListener(Object listenerType, IObservablesListener listener)
      Parameters:
      listenerType - arbitrary object to identify a type of the listener
      listener - the listener to remove; not null

      protected void fireEvent(ObservableEvent event)

    • getRealm

      public Realm getRealm()
      Returns:
      Returns the realm.

    • clone
