    The constructor of the StringPropertyBase.

• Method Detail

  • 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 String> 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 String> 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 is called when the value is changed, either manually by calling set(java.lang.String) or in case of a bound property, if the binding becomes invalid.

  • invalidated

    protected void invalidated()

    The method invalidated() can be overridden to receive invalidation notifications. This is the preferred option in Objects defining the property, because it requires less memory. The default implementation is empty.

  • get

    public String get()

    Get the wrapped value. This must be identical to the value returned from WritableValue.getValue().

    This method exists only to align WritableObjectValue API with WritableBooleanValue and subclasses of WritableNumberValue

    Returns:

    The current value

  • set

    public void set(String newValue)

    Set the wrapped value. Should be equivalent to WritableValue.setValue(java.lang.Object)

    Parameters:

    newValue - The new value

    See Also:

    WritableObjectValue.get()

  • isBound

    public boolean isBound()

    Can be used to check, if a Property is bound.

    Returns:

    true if the Property is bound, false otherwise

    See Also:

    Property.bind(javafx.beans.value.ObservableValue)

  • bind

    public void bind(ObservableValue<? extends String> newObservable)

    Create a unidirection binding for this Property.

    Note that JavaFX has all the bind calls implemented through weak listeners. This means the bound property can be garbage collected and stopped from being updated.

    Parameters:

    newObservable - The observable this Property should be bound to.

  • unbind

    public void unbind()

    Remove the unidirectional binding for this Property. If the Property is not bound, calling this method has no effect.

    See Also:

    Property.bind(javafx.beans.value.ObservableValue)

  • toString

    public String toString()

    Returns a string representation of this StringPropertyBase object.

    Overrides:

    toString in class StringProperty

    Returns:

    a string representation of this StringPropertyBase object.
