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 | 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 | 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 eitherInvalidationListener 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 withObservableValues, 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 |
