- All Implemented Interfaces:
    `NumberExpression`, `Observable`, `Property<Number>`, `ReadOnlyProperty<Number>`, `ObservableDoubleValue`, `ObservableNumberValue`, `ObservableValue<Number>`, `WritableDoubleValue`, `WritableNumberValue`, `WritableValue<Number>`

      public class ReadOnlyDoubleWrapper
      extends SimpleDoubleProperty

  This class provides a convenient class to define read-only properties. It creates two properties that are synchronized. One property is read-only and can be passed to external users. The other property is read- and writable and should be used internally only.
  Since:
    JavaFX 2.0

- - ### Constructor Detail

    - #### ReadOnlyDoubleWrapper

          public ReadOnlyDoubleWrapper()

      The constructor of `ReadOnlyDoubleWrapper`

    - #### ReadOnlyDoubleWrapper

          public ReadOnlyDoubleWrapper​(double initialValue)

      The constructor of `ReadOnlyDoubleWrapper`
      Parameters:
        `initialValue` - the initial value of the wrapped value

    - #### ReadOnlyDoubleWrapper

          public ReadOnlyDoubleWrapper​(Object bean,
                                       String name)

      The constructor of `ReadOnlyDoubleWrapper`
      Parameters:
        `bean` - the bean of this `ReadOnlyDoubleProperty`
        `name` - the name of this `ReadOnlyDoubleProperty`

    - #### ReadOnlyDoubleWrapper

          public ReadOnlyDoubleWrapper​(Object bean,
                                       String name,
                                       double initialValue)

      The constructor of `ReadOnlyDoubleWrapper`
      Parameters:
        `bean` - the bean of this `ReadOnlyDoubleProperty`
        `name` - the name of this `ReadOnlyDoubleProperty`
        `initialValue` - the initial value of the wrapped value

  - ### Method Detail

    - #### getReadOnlyProperty

          public ReadOnlyDoubleProperty getReadOnlyProperty()

      Returns the read-only property, that is synchronized with this `ReadOnlyDoubleWrapper`.
      Returns:
        the read-only property

    - #### 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 `DoublePropertyBase.set(double)` or in case of a bound property, if the binding becomes invalid.
      Overrides:
        `fireValueChangedEvent` in class `DoublePropertyBase`
