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

      public class ReadOnlyLongWrapper
      extends SimpleLongProperty

  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

    - #### ReadOnlyLongWrapper

          public ReadOnlyLongWrapper()

      The constructor of `ReadOnlyLongWrapper`

    - #### ReadOnlyLongWrapper

          public ReadOnlyLongWrapper​(long initialValue)

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

    - #### ReadOnlyLongWrapper

          public ReadOnlyLongWrapper​(Object bean,
                                     String name)

      The constructor of `ReadOnlyLongWrapper`
      Parameters:
        `bean` - the bean of this `ReadOnlyLongProperty`
        `name` - the name of this `ReadOnlyLongProperty`

    - #### ReadOnlyLongWrapper

          public ReadOnlyLongWrapper​(Object bean,
                                     String name,
                                     long initialValue)

      The constructor of `ReadOnlyLongWrapper`
      Parameters:
        `bean` - the bean of this `ReadOnlyLongProperty`
        `name` - the name of this `ReadOnlyLongProperty`
        `initialValue` - the initial value of the wrapped value

  - ### Method Detail

    - #### getReadOnlyProperty

          public ReadOnlyLongProperty getReadOnlyProperty()

      Returns the readonly property, that is synchronized with this `ReadOnlyLongWrapper`.
      Returns:
        the readonly 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 `LongPropertyBase.set(long)` or in case of a bound property, if the binding becomes invalid.
      Overrides:
        `fireValueChangedEvent` in class `LongPropertyBase`
