032/**
033 * This class provides a full implementation of a {@link Property} wrapping an
034 * arbitrary {@code Object}.
035 *
036 * The value of a {@code ObjectProperty} can be get and set with {@link #get()},
037 * {@link #getValue()}, {@link #set(Object)}, and {@link #setValue(Object)}.
038 *
039 * A property can be bound and unbound unidirectional with
040 * {@link #bind(ObservableValue)} and {@link #unbind()}. Bidirectional bindings
041 * can be created and removed with {@link #bindBidirectional(Property)} and
042 * {@link #unbindBidirectional(Property)}.
043 *
044 * The context of a {@code ObjectProperty} can be read with {@link #getBean()}
045 * and {@link #getName()}.
046 *
047 * For specialized implementations for {@link ObservableList}, {@link ObservableSet} and
048 * {@link ObservableMap} that also report changes inside the collections, see
049 * {@link ListProperty}, {@link SetProperty} and {@link MapProperty}, respectively.
