Package javafx.beans.value

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

See: Description

Interface Summary

Interface	Description
ChangeListener<T>	A ChangeListener is notified whenever the value of an ObservableValue changes.
ObservableBooleanValue	An observable boolean value.
ObservableDoubleValue	An observable double value.
ObservableFloatValue	An observable float value.
ObservableIntegerValue	An observable integer value.
ObservableListValue<E>	An observable reference to an ObservableList.
ObservableLongValue	An observable long value.
ObservableMapValue<K,V>	An observable reference to an ObservableMap.
ObservableNumberValue	A common interface of all sub-interfaces of ObservableValue that wrap a number.
ObservableObjectValue<T>	An observable typed Object value.
ObservableSetValue<E>	An observable reference to an ObservableSet.
ObservableStringValue	An observable String value.
ObservableValue<T>	An ObservableValue is an entity that wraps a value and allows to observe the value for changes.
WritableBooleanValue	A writable boolean value.
WritableDoubleValue	A writable double value.
WritableFloatValue	A writable float value.
WritableIntegerValue	A writable int value.
WritableListValue<E>	A writable reference to an ObservableList.
WritableLongValue	A writable long value.
WritableMapValue<K,V>	A writable reference to an ObservableMap.
WritableNumberValue	A tagging interface that marks all sub-interfaces of WritableValue that wrap a number.
WritableObjectValue<T>	A writable typed value.
WritableSetValue<E>	A writable reference to an ObservableSet.
WritableStringValue	A writable String.
WritableValue<T>	A WritableValue is an entity that wraps a value that can be read and set.

Class Summary

Class	Description
ObservableValueBase<T>	A convenience class for creating implementations of ObservableValue.
WeakChangeListener<T>	A WeakChangeListener can be used, if an ObservableValue should only maintain a weak reference to the listener.

Package javafx.beans.value Description

The package javafx.beans.value contains the two fundamental interfaces ObservableValue and 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 InvalidationListener or ChangeListener. To allow working with primitive types directly a number of sub-interfaces are defined.

Type	Sub-interface of ObservableValue
boolean	ObservableBooleanValue
double	ObservableDoubleValue
float	ObservableFloatValue
int	ObservableIntegerValue
long	ObservableLongValue
double, float, int, long	ObservableNumberValue
Object	ObservableObjectValue
String	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.

Type	Sub-interface of WritableValue
boolean	WritableBooleanValue
double	WritableDoubleValue
float	WritableFloatValue
int	WritableIntegerValue
long	WritableLongValue
double, float, int, long	WritableNumberValue
Object	WritableObjectValue
String	WritableStringValue
