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

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

If the logged in user has read permission for the parent, READ 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. This class can be used even if the immediate parent isn't a shareable item, as long as it is possible for a child item to follow a chain of association to the actual parent where the permissions are set. For example BioAssay --> BioAssaySet --> Experiment.
