All Implemented Interfaces:

ICOSObjectVisitor

Direct Known Subclasses:

COSObjectWalkerDeep

public class COSObjectWalkerShallow
extends Object
implements ICOSObjectVisitor

Adapter implementation for visiting a COS object structure without navigating the indirect references.

More precise, this one will visit the directed acyclic data structure originating from a COS object.
