public final class ReadOnlyJavaBeanDoubleProperty
extends ReadOnlyDoublePropertyBase
implements ReadOnlyJavaBeanProperty<Number>

A ReadOnlyJavaBeanDoubleProperty provides an adapter between a regular read only Java Bean property of type double or Double and a JavaFX ReadOnlyDoubleProperty. It cannot be created directly, but a ReadOnlyJavaBeanDoublePropertyBuilder has to be used.

As a minimum, the Java Bean must implement a getter for the property. If the getter of an instance of this class is called, the property of the Java Bean is returned. If the Java Bean property is bound (i.e. it supports PropertyChangeListeners), this ReadOnlyJavaBeanDoubleProperty will be aware of changes in the Java Bean. Otherwise it can be notified about changes by calling fireValueChangedEvent().

Since:

JavaFX 2.1

Method Detail

get

public double get()

Returns the current value of this ObservableDoubleValue.

Specified by:

get in interface ObservableDoubleValue

Returns:

The current value

Throws:

UndeclaredThrowableException - if calling the getter of the Java Bean property throws an IllegalAccessException or an InvocationTargetException.

getBean

public Object getBean()

Returns the Object that contains this property. If this property is not contained in an Object, null is returned.

Specified by:

getBean in interface ReadOnlyProperty<Number>

Returns:

the containing Object or null

getName

public String getName()

Returns the name of this property. If the property does not have a name, this method returns an empty String.

Specified by:

getName in interface ReadOnlyProperty<Number>

Returns:

the name or an empty String

fireValueChangedEvent

public void fireValueChangedEvent()

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

Specified by:

fireValueChangedEvent in interface ReadOnlyJavaBeanProperty<Number>

Overrides:

fireValueChangedEvent in class ReadOnlyDoublePropertyBase

dispose

public void dispose()

Signals to the JavaFX property that it will not be used anymore and any references can be removed. A call of this method usually results in the property stopping to observe the Java Bean property by unregistering its listener(s).

Specified by:

dispose in interface ReadOnlyJavaBeanProperty<Number>
