void |
addListener(ChangeListener<? super ObservableMap<K,V>> listener)
Adds a
ChangeListener which will be notified whenever the value
of the ObservableValue changes. |
void |
addListener(InvalidationListener listener)
Adds an
InvalidationListener which will be notified whenever the
Observable becomes invalid. |
void |
addListener(MapChangeListener<? super K,? super V> listener)
Add a listener to this observable map.
|
ReadOnlyBooleanProperty |
emptyProperty()
A boolean property that is
true, if the map is empty. |
ObservableMap<K,V> |
get()
Returns the current value of this
ObservableObjectValue<T>. |
java.lang.Object |
getBean()
Returns the
Object that contains this property. |
java.lang.String |
getName()
Returns the name of this property.
|
void |
removeListener(ChangeListener<? super ObservableMap<K,V>> listener)
Removes the given listener from the list of listeners, that are notified
whenever the value of the
ObservableValue changes. |
void |
removeListener(InvalidationListener listener)
Removes the given listener from the list of listeners, that are notified
whenever the value of the
Observable becomes invalid. |
void |
removeListener(MapChangeListener<? super K,? super V> listener)
Tries to removed a listener from this observable list.

ObservableObjectValueObservableObjectValue<T>.public void addListener(InvalidationListener listener)
ObservableInvalidationListener which will be notified whenever the
Observable becomes invalid. If the same
listener is added more than once, then it will be notified more than
once. That is, no check is made to ensure uniqueness.
Note that the same actual InvalidationListener instance may be
safely registered for different Observables.
The Observable stores a strong reference to the listener
which will prevent the listener from being garbage collected and may
result in a memory leak. It is recommended to either unregister a
listener by calling removeListener after use or to use an instance of
WeakInvalidationListener avoid this situation.

If the given listener has not been previously registered (i.e. it was never added) then this method call is a no-op. If it had been previously added then it will be removed. If it had been added more than once, then only the first occurrence will be removed.

ObservableValueChangeListener which will be notified whenever the value

check is made to ensure uniqueness.
Note that the same actual ChangeListener instance may be safely
