ReadOnlyDoublePropertyBase

public ReadOnlyDoublePropertyBase()

Creates a default ReadOnlyDoublePropertyBase.

Method Details

addListener

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 Number> 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 Number> 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)

fireValueChangedEvent

protected void fireValueChangedEvent()

Sends notifications to all attached InvalidationListeners and ChangeListeners. This method needs to be called, if the value of this property changes.
