# Class ReadOnlySetWrapper<E>

java.lang.Object
javafx.beans.binding.SetExpression<E>
javafx.beans.property.ReadOnlySetProperty<E>
javafx.beans.property.SetProperty<E>
javafx.beans.property.SetPropertyBase<E>
javafx.beans.property.SimpleSetProperty<E>
javafx.beans.property.ReadOnlySetWrapper<E>

Type Parameters:
  `E` - the set element type

All Implemented Interfaces:
  `Iterable<E>`, `Collection<E>`, `Set<E>`, `Observable`, `Property<ObservableSet<E>>`, `ReadOnlyProperty<ObservableSet<E>>`, `ObservableObjectValue<ObservableSet<E>>`, `ObservableSetValue<E>`, `ObservableValue<ObservableSet<E>>`, `WritableObjectValue<ObservableSet<E>>`, `WritableSetValue<E>`, `WritableValue<ObservableSet<E>>`, `ObservableSet<E>`

public class ReadOnlySetWrapper<E> extends SimpleSetProperty<E>
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 2.1
