Class SetProperty<E>

java.lang.Object

javafx.beans.binding.SetExpression<E>

javafx.beans.property.ReadOnlySetProperty<E>

javafx.beans.property.SetProperty<E>

Type Parameters:

E - the type of the Set elements

All Implemented Interfaces:

Iterable<E>, Collection<E>, Set<E>, Observable, Property<ObservableSet<E>>, ReadOnlyProperty<ObservableSet<E>>, ObservableObjectValue<ObservableSet<E>>, ObservableSetValue<E>, ObservableValue<ObservableSet<E>>, WritableObjectValue<ObservableSet<E>>, WritableSetValue<E>, WritableValue<ObservableSet<E>>, ObservableSet<E>

Direct Known Subclasses:

SetPropertyBase

public abstract class SetProperty<E>
extends ReadOnlySetProperty<E>
implements Property<ObservableSet<E>>, WritableSetValue<E>

This class provides a full implementation of a Property wrapping an ObservableSet. The value of a SetProperty can be get and set with ObservableObjectValue.get(), SetExpression.getValue(), WritableObjectValue.set(Object), and setValue(ObservableSet). A property can be bound and unbound unidirectional with Property.bind(javafx.beans.value.ObservableValue) and Property.unbind(). Bidirectional bindings can be created and removed with bindBidirectional(Property) and unbindBidirectional(Property). The context of a SetProperty can be read with ReadOnlyProperty.getBean() and ReadOnlyProperty.getName().

Since:

JavaFX 2.1

Constructor Details

SetProperty

public SetProperty()

Creates a default SetProperty.

Method Details

setValue

public void setValue(ObservableSet<E> v)

Set the wrapped value.

Specified by:

setValue in interface WritableValue<E>

Parameters:

v - The new value

bindBidirectional

public void bindBidirectional(Property<ObservableSet<E>> other)

Create a bidirectional binding between this Property and 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:

bindBidirectional in interface Property<E>

Parameters:

other - the other Property

unbindBidirectional

public void unbindBidirectional(Property<ObservableSet<E>> other)

Removes a bidirectional binding between this Property and 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.bindBidirectional(property2);
    property2.unbindBidirectional(property1);

Specified by:

unbindBidirectional in interface Property<E>

Parameters:

other - the other Property

toString

public String toString()

Returns a string representation of this SetProperty object.

Overrides:

toString in class ReadOnlySetProperty<E>

Returns:

a string representation of this SetProperty object.
