public abstract class DTMDefaultBaseTraversers extends DTMDefaultBase
This class implements the traversers for DTMDefaultBase.PLEASE NOTE that the public interface for all traversers should be in terms of DTM Node Handles... but they may use the internal node identity indices within their logic, for efficiency's sake. Be very careful to avoid confusing these when maintaining this code.
