public final class JavaBeanObjectProperty<T> extends ObjectProperty<T> implements JavaBeanProperty<T>
AJavaBeanObjectPropertyprovides an adapter between a regular Java Bean property of typeTand a JavaFXObjectProperty<T>. It cannot be created directly, but aJavaBeanObjectPropertyBuilderhas to be used.As a minimum, the Java Bean class must implement a getter and a setter for the property. The class, as well as the getter and a setter methods, must be declared public. If the getter of an instance of this class is called, the property of the Java Bean is returned. If the setter is called, the value will be passed to the Java Bean property. If the Java Bean property is bound (i.e. it supports PropertyChangeListeners), this
JavaBeanObjectPropertywill be aware of changes in the Java Bean. Otherwise it can be notified about changes by callingReadOnlyJavaBeanProperty.fireValueChangedEvent(). If the Java Bean property is also constrained (i.e. it supports VetoableChangeListeners), thisJavaBeanObjectPropertywill reject changes, if it is bound to anObservableValue<Object>.Deploying an Application as a Module
If the Java Bean class is in a named module, then it must be reflectively accessible to the
javafx.basemodule. A class is reflectively accessible if the moduleopensthe containing package to at least thejavafx.basemodule.For example, if
com.foo.MyBeanClassis in thefoo.appmodule, themodule-info.javamight look like this:module foo.app { opens com.foo to javafx.base; }Alternatively, a class is reflectively accessible if the module
exportsthe containing package unconditionally.- Since:

Method Detail
-
get
public T get()
Get the wrapped value. This must be identical to the value returned fromWritableValue.getValue().This method exists only to align WritableObjectValue API with
WritableBooleanValueand subclasses ofWritableNumberValue- Specified by:
getin interfaceObservableObjectValue<T>- Specified by:
getin interfaceWritableObjectValue<T>- Returns:
- The current value
- Throws:
UndeclaredThrowableException- if calling the getter of the Java Bean property throws anIllegalAccessExceptionor anInvocationTargetException.
-
set
public void set(T value)
Set the wrapped value. Should be equivalent toWritableValue.setValue(java.lang.Object)- Specified by:
setin interfaceWritableObjectValue<T>- Parameters:
value- The new value- Throws:
UndeclaredThrowableException- if calling the getter of the Java Bean property throws anIllegalAccessExceptionor anInvocationTargetException.- See Also:
WritableObjectValue.get()
-
toString
public String toString()
Returns a string representation of thisJavaBeanObjectPropertyobject.- Overrides:
toStringin classObjectProperty<T>- Returns:
- a string representation of this
JavaBeanObjectPropertyobject.
