Interface ModelVisitor

All Known Implementing Classes:

TreeViewVisitor

public interface ModelVisitor

Visitor that allows for visiting of IViewable interface objects. Because of the nature of the Visitor pattern, every time a new object is added that derives from IViewable, you need to modify the ViewVisitor interface appropriately.

Each visit may throw a ViewVisitorException which is a runtime exception. You may catch it while processing the nodes if you wish.
