Package javafx.beans.value

The package javafx.beans.value contains the two fundamental interfaces javafx.beans.value.ObservableValue and javafx.beans.value.WritableValue and all of its sub-interfaces.

ObservableValue

An ObservableValue wraps a value that can be read and observed for invalidations and changes. Listeners have to implement either javafx.beans.InvalidationListener or javafx.beans.value.ChangeListener. To allow working with primitive types directly a number of sub-interfaces are defined.
ObservableValue Table
Type Sub-interface of ObservableValue
boolean javafx.beans.value.ObservableBooleanValue
double javafx.beans.value.ObservableDoubleValue
float javafx.beans.value.ObservableFloatValue
int javafx.beans.value.ObservableIntegerValue
long javafx.beans.value.ObservableLongValue
double, float, int, long javafx.beans.value.ObservableNumberValue
Object javafx.beans.value.ObservableObjectValue
String javafx.beans.value.ObservableStringValue

WritableValue

A WritableValue wraps a value that can be read and set. As with ObservableValues, a number of sub-interfaces are defined to work with primitive types directly.
WritableValue Table
Type Sub-interface of WritableValue
boolean javafx.beans.value.WritableBooleanValue
double javafx.beans.value.WritableDoubleValue
float javafx.beans.value.WritableFloatValue
int javafx.beans.value.WritableIntegerValue
long javafx.beans.value.WritableLongValue
double, float, int, long javafx.beans.value.WritableNumberValue
Object javafx.beans.value.WritableObjectValue
String javafx.beans.value.WritableStringValue

Class Summary

Modifier and TypeClass and Description
public abstract class
ObservableValueBase<
the observable value type
T>

A convenience class for creating implementations of ObservableValue.

public class
WeakChangeListener<
The type of the observed value
T>

A WeakChangeListener can be used if an ObservableValue should only maintain a weak reference to the listener.
