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.
