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.
