This class provides a full implementation of a Property wrapping an arbitrary Object. The value of a ObjectProperty can be get and set with WritableObjectValue.get(), ObjectExpression.getValue(), WritableObjectValue.set(Object), and setValue(Object). A property can be bound and unbound unidirectional with Property.bind(ObservableValue) and Property.unbind(). Bidirectional bindings can be created and removed with bindBidirectional(Property) and unbindBidirectional(Property). The context of a ObjectProperty can be read with ReadOnlyProperty.getBean() and ReadOnlyProperty.getName(). For specialized implementations for ObservableList, ObservableSet and ObservableMap that also report changes inside the collections, see ListProperty, SetProperty and MapProperty, respectively.
Type parameters:
  • <T> – the type of the wrapped Object
