public class ReadOnlyLongWrapper
extends SimpleLongProperty
This class provides a convenient class to define read-only properties. It creates two properties that are synchronized. One property is read-only and can be passed to external users. The other property is read- and writable and should be used internally only.

JavaFX 2.0

    • addListener

      public void addListener(InvalidationListener listener)
      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.

      Specified by:

      addListener in interface Observable

      Overrides:

      addListener in class LongPropertyBase

      Parameters:

      listener - The listener to register

      See Also:

      Observable.removeListener(InvalidationListener)

    • removeListener

      public void removeListener(InvalidationListener listener)
      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.

      Specified by:

      removeListener in interface Observable

      Overrides:

      removeListener in class LongPropertyBase

      Parameters:

      listener - The listener to remove

      See Also:

      Observable.addListener(InvalidationListener)

    • addListener

      public void addListener(ChangeListener<? super Number> listener)
      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.

      Specified by:

      addListener in interface ObservableValue<Number>

      Overrides:

      addListener in class LongPropertyBase

      Parameters:

      listener - The listener to register

      See Also:

      ObservableValue.removeListener(ChangeListener)

    • removeListener

      public void removeListener(ChangeListener<? super Number> listener)
      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.

      Specified by:

      removeListener in interface ObservableValue<Number>

      Overrides:

      removeListener in class LongPropertyBase

      Parameters:

      listener - The listener to remove

      See Also:

      ObservableValue.addListener(ChangeListener)

    • fireValueChangedEvent

      protected void fireValueChangedEvent()
      Sends notifications to all attached InvalidationListeners and ChangeListeners. This method is called when the value is changed, either manually by calling LongPropertyBase.set(long) or in case of a bound property, if the binding becomes invalid.

      Overrides:

      fireValueChangedEvent in class LongPropertyBase
