Method Detail

getTarget

public ShapeDeleter getTarget()
Description copied from interface: IMapping
Returns the target object of the mapping. If there is several target objects, a collection is returned.

Returns:
The source object of the mapping.

onObjectAdded

public void onObjectAdded(java.lang.Object list,
                          java.lang.Object object,
                          int index)
Description copied from interface: IMapping
Executes the mapping for the addition of an object.

Specified by:
onObjectAdded in interface IMapping
Overrides:
onObjectAdded in class SelectionMapping
Parameters:
list - The modified source list.
object - The added object.
index - The position where the object has been added. -1 = the last position.

onObjectRemoved

public void onObjectRemoved(java.lang.Object list,
