NAME

       Iterator - marks a position in a data structure

SYNOPSIS

       #include <Unidraw/iterator.h>

DESCRIPTION

       An  iterator  marks  a  position in a data structure, generally during a traversal of some
       sort.  For example, an iterator keeps track of the current position when iterating through
       a  list  of  elements.   Unidraw's  Iterator class serves this purpose in conjunction with
       ULists or objects that use them.

PUBLIC OPERATIONS

       Iterator()
       Iterator(Iterator&)
              Construct a new iterator.  The second constructor initializes the iterator's  value
              to that of the given iterator.

       virtual void SetValue(void*)
       virtual void* GetValue()
              Classes  that  use  an  iterator  must  store  position  information  in it.  These
              operations set and get the this information.
