        public void addListener​(InvalidationListener listener)
        Description copied from interface: Observable
        Adds an InvalidationListener 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.

        Parameters:
        listener - The listener to register
        See Also:
        Observable.removeListener(InvalidationListener)
      • removeListener

        public void removeListener​(InvalidationListener listener)
        Description copied from interface: Observable
        Removes the given listener from the list of listeners, that are notified whenever the value of the Observable 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:
        Observable.addListener(InvalidationListener)
      • addListener

        public void addListener​(ChangeListener<? super ObservableMap<K,V>> listener)
        Description copied from interface: ObservableValue
        Adds a ChangeListener which will be notified whenever the value of the ObservableValue 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 different ObservableValues.

        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 calling removeListener after use or to use an instance of WeakChangeListener avoid this situation.

        Parameters:
        listener - The listener to register
        See Also:
        ObservableValue.removeListener(ChangeListener)
      • removeListener

        public void removeListener​(ChangeListener<? super ObservableMap<K,V>> listener)
        Description copied from interface: ObservableValue
        Removes the given listener from the list of listeners, that are notified whenever the value of the ObservableValue 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:
        ObservableValue.addListener(ChangeListener)
      • addListener

        public void addListener​(MapChangeListener<? super K,? super V> listener)
        Description copied from interface: ObservableMap
        Add a listener to this observable map.
        Parameters:
        listener - the listener for listening to the list changes
      • removeListener

        public void removeListener​(MapChangeListener<? super K,? super V> listener)
        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
