Class SimpleListProperty<S,E>
java.lang.Object
org.eclipse.core.databinding.property.list.ListProperty<S,E>
org.eclipse.core.databinding.property.list.SimpleListProperty<S,E>
- Type Parameters:
S- type of the source objectE- type of the elements in the list
- All Implemented Interfaces:
IProperty,IListProperty<S,E>
- Direct Known Subclasses:
ViewerListProperty,WidgetListProperty
Simplified abstract implementation of IListProperty. This class takes care of
most of the functional requirements for an IListProperty implementation,
leaving only the property-specific details to subclasses.
Subclasses must implement these methods:
IListProperty.getElementType()doGetList(Object)doSetList(Object, List, ListDiff)adaptListener(ISimplePropertyListener)
In addition, we recommended overriding Object.toString() to return a
description suitable for debugging purposes.

adaptListener
public abstract INativePropertyListener<S> adaptListener(ISimplePropertyListener<S, ListDiff<E>> listener) Returns a listener capable of adding or removing itself as a listener on a source object using the the source's "native" listener API. Events received from the source objects are parlayed to the specified listener argument.This method returns null if the source object has no listener APIs for this property.
- Parameters:
listener- the property listener to receive events- Returns:
- a native listener which parlays property change events to the specified listener, or null if the source object has no listener APIs for this property.
- Restriction:
- This method is not intended to be referenced by clients.
