Class ReadOnlyObjectProperty<T>

java.lang.Object

javafx.beans.binding.ObjectExpression<T>

javafx.beans.property.ReadOnlyObjectProperty<T>

Type Parameters:

T - the type of the wrapped Object

All Implemented Interfaces:

Observable, ReadOnlyProperty<T>, ObservableObjectValue<T>, ObservableValue<T>

Direct Known Subclasses:

ObjectProperty, ReadOnlyObjectPropertyBase

public abstract class ReadOnlyObjectProperty<T>
extends ObjectExpression<T>
implements ReadOnlyProperty<T>

Superclass for all readonly properties wrapping an arbitrary Object. For specialized implementations for ObservableList, ObservableSet and ObservableMap that also report changes inside the collections, see ReadOnlyListProperty, ReadOnlySetProperty and ReadOnlyMapProperty, respectively.

Since:

JavaFX 2.0

Methods declared in interface ObservableValue

addListener, flatMap, map, orElse, removeListener, subscribe, subscribe, when

Modifier and Type	Method	Description
void	addListener(ChangeListener<? super T> listener)	Adds a ChangeListener which will be notified whenever the value of the ObservableValue changes.
default <U> ObservableValue<U>	flatMap(Function<? super T, ? extends ObservableValue<? extends U>> mapper)	Returns an ObservableValue that holds the value of an ObservableValue produced by applying the given mapping function on this value.

default ObservableValue<T>	orElse(T constant)	Returns an ObservableValue that holds this value, or the given constant if it is null.
void	removeListener(ChangeListener<? super T> listener)	Removes the given listener from the list of listeners that are notified whenever the value of the ObservableValue changes.
default Subscription	subscribe(BiConsumer<? super T, ? super T> changeSubscriber)	Creates a Subscription on this ObservableValue which calls the given changeSubscriber with the old and new value whenever its value changes.
default Subscription	subscribe(Consumer<? super T> valueSubscriber)	Creates a Subscription on this ObservableValue which immediately provides the current value to the given valueSubscriber, followed by any subsequent values whenever its value changes.
default ObservableValue<T>	when(ObservableValue<Boolean> condition)	Returns an ObservableValue that holds this value and is updated only when condition holds true.
