bool operator==(const regex_token_iterator& right) const;

Returns: true if *this and right are both end-of-sequence iterators, or if *this and right are both suffix iterators and suffix == right.suffix; otherwise returns false if *this or right is an end-of-sequence iterator or a suffix iterator. Otherwise returns true if position == right.position, N == right.N, and subs == right.subs. Otherwise returns false.

bool operator!=(const regex_token_iterator& right) const;

Returns: !(*this == right).
