Class iterator

Synopsis

#include "breeze/text/set_of_chars.hpp"

class               iterator

Description

An iterator for the set.

Iterates over all of the characters in the set. It is a constant forward iterator (iterator and const_iterator have the same semantics).

Iterator operations

	operator!=
	operator*
	operator++ overload
	operator==

Methods

	iterator overload	Constructs a one-past-the-end iterator.
	iterator overload	Constructs an iterator to the first character in sc.
