Class SetPropertyBase<E>

java.lang.Object

javafx.beans.binding.SetExpression<E>

javafx.beans.property.ReadOnlySetProperty<E>

javafx.beans.property.SetProperty<E>

javafx.beans.property.SetPropertyBase<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:: SimpleSetProperty

public abstract class SetPropertyBase<E>
extends SetProperty<E>

The class SetPropertyBase is the base class for a property wrapping an ObservableSet. It provides all the functionality required for a property except for the ReadOnlyProperty.getBean() and ReadOnlyProperty.getName() methods, which must be implemented by extending classes.

Since:: JavaFX 2.1
See Also:: ObservableSet, SetProperty

Constructor Details

SetPropertyBase

public SetPropertyBase()

The Constructor of SetPropertyBase

SetPropertyBase

public SetPropertyBase(ObservableSet<E> initialValue)

The constructor of the SetPropertyBase.

Parameters:: initialValue - the initial value of the wrapped value

Method Details

fireValueChangedEvent

protected void fireValueChangedEvent()

Sends notifications to all attached InvalidationListeners, ChangeListeners, and SetChangeListener. This method is called when the value is changed, either manually by calling WritableObjectValue.set(javafx.collections.ObservableSet) or in case of a bound property, if the binding becomes invalid.

fireValueChangedEvent

protected void fireValueChangedEvent(SetChangeListener.Change<? extends E> change)

Sends notifications to all attached InvalidationListeners, ChangeListeners, and SetChangeListener. This method is called when the content of the list changes.

Parameters:: change - the change that needs to be propagated

invalidated

protected void invalidated()

The method invalidated() can be overridden to receive invalidation notifications. This is the preferred option in Objects defining the property, because it requires less memory. The default implementation is empty.

toString

public String toString()

Returns a string representation of this SetPropertyBase object.

Overrides:: toString in class SetProperty<E>
Returns:: a string representation of this SetPropertyBase object.
