All Implemented Interfaces:

DropTargetListener, ImageObserver, MenuContainer, Serializable, EventListener, Accessible, Scrollable

public class NewClassTree
extends JTree
implements DropTargetListener

Object of this class is created when user wishes to create a new Storable Class.

DropTargetListner is implemented by this class (i.e this class is the target for the drag and drop process). Fields can be dragged from Class Browser, Field Browser and dropped on this new class. Before accepting the dropped field, all kind of validations are made and the element is added only when the field gets cleared by all validations.

Some of the validations that are made in this class are

1. Substructs cannot be added to base class.
2. Sub-Classes can only have sub-structs and arrays.
3. Fields can only be added to base class, array and sub-structs.
4. Portal allows only up to 2 level deep of array or substruct.
5. Existence of field in the current class.
