addListener
Description copied from interface:Observable
Adds anInvalidationListener
which will be notified whenever theObservable
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 differentObservables
.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 callingremoveListener
after use or to use an instance ofWeakInvalidationListener
avoid this situation.- Parameters:
listener
- The listener to register- See Also:
-
removeListener
Description copied from interface:Observable
Removes the given listener from the list of listeners, that are notified whenever the value of theObservable
becomes invalid.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.
- Parameters:
listener
- The listener to remove- See Also:
-
addListener
Description copied from interface:ObservableValue
Adds aChangeListener
which will be notified whenever the value of theObservableValue
changes. 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
ChangeListener
instance may be safely registered for differentObservableValues
.The
ObservableValue
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 callingremoveListener
after use or to use an instance ofWeakChangeListener
avoid this situation.- Parameters:
listener
- The listener to register- See Also:
-
removeListener
Description copied from interface:ObservableValue
Removes the given listener from the list of listeners that are notified whenever the value of theObservableValue
changes.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.
- Parameters:
listener
- The listener to remove- See Also:
-
addListener
Description copied from interface:ObservableMap
Add a listener to this observable map.- Parameters:
listener
- the listener for listening to the list changes
-
removeListener
Description copied from interface:ObservableMap
Tries to removed a listener from this observable map. If the listener is not attached to this map, nothing happens.- Parameters:
listener
- a listener to remove
-
fireValueChangedEvent
protected void fireValueChangedEvent()This method needs to be called if the reference to theObservableList
changes. It sends notifications to all attachedInvalidationListeners
,ChangeListeners
, andListChangeListener
. This method needs to be called, if the value of this property changes. -
fireValueChangedEvent
This method needs to be called if the content of the referencedObservableList
changes. Sends notifications to all attachedInvalidationListeners
,ChangeListeners
, andListChangeListener
. This method is called when the content of the list changes.- Parameters:
change
- the change that needs to be propagated
-
