public final class JavaBeanDoubleProperty
extends DoubleProperty
implements JavaBeanProperty<Number>

A JavaBeanDoubleProperty provides an adapter between a regular Java Bean property of type double or Double and a JavaFX DoubleProperty. It cannot be created directly, but a JavaBeanDoublePropertyBuilder has 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 JavaBeanDoubleProperty will be aware of changes in the Java Bean. Otherwise it can be notified about changes by calling ReadOnlyJavaBeanProperty.fireValueChangedEvent(). If the Java Bean property is also constrained (i.e. it supports VetoableChangeListeners), this JavaBeanDoubleProperty will reject changes, if it is bound to an ObservableValue<Double>.

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.base module. A class is reflectively accessible if the module opens the containing package to at least the javafx.base module.

For example, if com.foo.MyBeanClass is in the foo.app module, the module-info.java might look like this:

module foo.app {
    opens com.foo to javafx.base;
}

Alternatively, a class is reflectively accessible if the module exports the containing package unconditionally.

JavaFX 2.1

Method Detail

get

public double get()

Get the wrapped value. Unlike WritableValue.getValue(), this method returns primitive double. Needs to be identical to WritableValue.getValue().

Specified by:

get in interface ObservableDoubleValue

Specified by:

get in interface WritableDoubleValue

Returns:

The current value

Throws:

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

set

public void set(double value)

Set the wrapped value. Unlike WritableDoubleValue.setValue(java.lang.Number), this method uses primitive double.

Specified by:

set in interface WritableDoubleValue

Parameters:

value - The new value

Throws:

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

toString

public String toString()

Returns a string representation of this JavaBeanDoubleProperty object.

Overrides:

toString in class DoubleProperty

Returns:

a string representation of this JavaBeanDoubleProperty object.
