Package javafx.beans
javafx.beans contains the interfaces that define the most generic form of observability.See: Description
| Interface | Description |
|---|---|
| InvalidationListener | An InvalidationListener is notified whenever an Observable becomes invalid. |
| Observable | An Observable is an entity that wraps content and allows to observe the content for invalidations. |
| WeakListener | WeakListener is the super interface of all weak listener implementations JavaFX runtime. |
| Class | Description |
|---|---|
| WeakInvalidationListener | A WeakInvalidationListener can be used, if an Observable should only maintain a weak reference to the listener. |
| Annotation Type | Description |
|---|---|
| DefaultProperty | Specifies a property to which child elements will be added or set when an explicit property is not given. |
| NamedArg | Annotation that provides information about argument's name. |
Package javafx.beans Description
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 Observable interface.
An implementation of Observable allows to attach an InvalidationListener. The contentBinding gets notified every time the Observable may have changed. Typical implementations of Observable are all properties, all bindings, ObservableList, and 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 ChangeListener for properties and bindings, ListChangeListener for ObservableLists or MapChangeListener for ObservableMap instead.
