Interface ListElementInfo

All Superinterfaces:

ItsNatUserData

public interface ListElementInfo
extends ItsNatUserData

Contains the DOM Element object and index of a child of a DOM element list.

If the parent list (which this object belongs to) is master, this object is ever the same instance per list element, supporting index changes (inserting or removing elements to the list) and DOM element changes (calling ElementListFree.setElementAt(int,org.w3c.dom.Element) ). This feature is very interesting to save contextual data associated to the child element (using ItsNatUserData).

If the parent list is slave every object obtained is a new instance, ItsNatUserData can not be used.
