JavaFX 27 · javafx.beans · APIdia, the JavaDoc alternative

The package javafx.beans contains the interfaces that define the most generic form of observability. All other classes in the JavaFX library, that are observable, extend the javafx.beans.Observable interface.

An implementation of Observable allows to attach an javafx.beans.InvalidationListener. The contentBinding gets notified every time the Observable may have changed. Typical implementations of Observable are all properties, all bindings, javafx.collections.ObservableList, and javafx.collections.ObservableMap.

An InvalidationListener will get no further information, e.g. it will not get the old and the new value of a property. If you need more information consider using a javafx.beans.value.ChangeListener for properties and bindings, javafx.collections.ListChangeListener for ObservableLists or javafx.collections.MapChangeListener for ObservableMap instead.
