Class ObjectProperty<T>
- javafx.beans.binding.ObjectExpression<T>
-
- javafx.beans.property.ReadOnlyObjectProperty<T>
-
- javafx.beans.property.ObjectProperty<T>
Type Parameters:
T - the type of the wrapped Object
All Implemented Interfaces:
Observable, Property<T>, ReadOnlyProperty<T>, ObservableObjectValue<T>, ObservableValue<T>, WritableObjectValue<T>, WritableValue<T>
Direct Known Subclasses:
public abstract class ObjectProperty<T> extends ReadOnlyObjectProperty<T> implements Property<T>, WritableObjectValue<T>
Property wrapping an arbitrary Object. The value of a ObjectProperty can be get and set with ObservableObjectValue.get(), ObjectExpression.getValue(), WritableObjectValue.set(Object), and setValue(Object). A property can be bound and unbound unidirectional with Property.bind(ObservableValue) and Property.unbind(). Bidirectional bindings can be created and removed with bindBidirectional(Property) and unbindBidirectional(Property). The context of a ObjectProperty can be read with ReadOnlyProperty.getBean() and ReadOnlyProperty.getName(). For specialized implementations for ObservableList, ObservableSet and ObservableMap that also report changes inside the collections, see ListProperty, SetProperty and MapProperty, respectively.Since:

setValue
public void setValue(T v)
Set the wrapped value.Specified by:
setValuein interfaceWritableValue<T>Parameters:
v- The new value
-
bindBidirectional
public void bindBidirectional(Property<T> other)
Create a bidirectional binding between thisPropertyand another one. Bidirectional bindings exists independently of unidirectional bindings. So it is possible to add unidirectional binding to a property with bidirectional binding and vice-versa. However, this practice is discouraged.It is possible to have multiple bidirectional bindings of one Property.
JavaFX bidirectional binding implementation use weak listeners. This means bidirectional binding does not prevent properties from being garbage collected.
Specified by:
bindBidirectionalin interfaceProperty<T>Parameters:
other- the otherProperty
-
unbindBidirectional
public void unbindBidirectional(Property<T> other)
Remove a bidirectional binding between thisPropertyand another one. If no bidirectional binding between the properties exists, calling this method has no effect. It is possible to unbind by a call on the second property. This code will work:property1.bindBirectional(property2); property2.unbindBidirectional(property1);Specified by:
unbindBidirectionalin interfaceProperty<T>Parameters:
other- the otherProperty
-
toString
public String toString()
Returns a string representation of thisObjectPropertyobject.Overrides:
toStringin classReadOnlyObjectProperty<T>Returns:
a string representation of this
ObjectPropertyobject.
