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
