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.
