Constructor Detail

BidiObservableMap

public BidiObservableMap(
IObservableMap wrappedMap)
Constructs a BidirectionalMap tracking the given observable map.

Parameters:
wrappedMap - the observable map to track
Method Detail

firstListenerAdded

protected void firstListenerAdded()
Overrides:
firstListenerAdded in class DecoratingObservableMap

lastListenerRemoved

protected void lastListenerRemoved()
Overrides:
lastListenerRemoved in class DecoratingObservableMap

handleMapChange

protected void handleMapChange(
MapChangeEvent 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
Parameters:
event - the change event received from the decorated observable

containsValue

public boolean containsValue(
Object value)
Specified by:
containsValue in interface Map
Specified by:
containsValue in interface IObservableMap
Overrides:
containsValue in class DecoratingObservableMap

getKeys

public 
Set 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

addListener

protected void addListener(
Object listenerType,
                           
IObservablesListener listener)
Parameters:
listenerType -
listener -

removeListener

protected void removeListener(
Object listenerType,
                              
IObservablesListener listener)
Parameters:
listenerType -
listener -

hasListeners

protected boolean hasListeners()

fireEvent

protected void fireEvent(
ObservableEvent event)

getRealm

public 
Realm getRealm()
Returns:
Returns the realm.

clone

protected 
Object clone()
                throws
