abstract class BasicChildItem<D extends BasicData>
extends BasicItem<D>

An abstract base class for all items which are child items to a BasicItem parent item. This class implements the initPermissions(int, int) method and sets the permissions for the child item based on the permissions for type of the parent item.

If the logged in user has read/use permission for the parent, READ/USE permission is granted. If the logged in user has write permission for the parent, WRITE, DELETE and CREATE permission is granted.

This class should only be used if the parent item itself hasn't overridden the initPermissions method, since that method is never called.
