Interface IVisitor

All Known Implementing Classes:

Cloner, Visitor

public interface IVisitor

Visitor interface. Implementations are expected to be functional (traversal results are propagated through return values rather than side effects) and external (responsibility for traversing the hierarchical structure is assigned to the 'visit' methods rather than the 'accept' counterparts).
