035 * This class provides a full implementation of a {@link Property} wrapping a
036 * {@link javafx.collections.ObservableSet}.
037 *
038 * The value of a {@code SetProperty} can be get and set with {@link #get()},
039 * {@link #getValue()}, {@link #set(Object)}, and {@link #setValue(ObservableSet)}.
040 *
041 * A property can be bound and unbound unidirectional with
042 * {@link #bind(javafx.beans.value.ObservableValue)} and {@link #unbind()}. Bidirectional bindings
043 * can be created and removed with {@link #bindBidirectional(Property)} and
044 * {@link #unbindBidirectional(Property)}.
045 *
046 * The context of a {@code SetProperty} can be read with {@link #getBean()}
047 * and {@link #getName()}.
