# Iterator(3)

marks a position in a data structure

## 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.
