std::regex_token_iterator<BidirIt,CharT,Traits>::operator==, operator!= - cppreference.com

From cppreference.com

bool operator==( const regex_token_iterator& other ) const;
(1) (since C++11)
bool operator!=( const regex_token_iterator& other ) const;
(2) (since C++11)
(until C++20)

Checks whether *this and other are equivalent.

Two regex token iterators are equal if:

a) They are both end-of-sequence iterators.

b) They are both suffix iterators and the suffixes are equal.

c) Neither of them is end-of-sequence or suffix iterator and:

  • position == other.position
  • N == other.N
  • subs == other.subs

1) Checks whether *this is equal to other.

2) Checks whether *this is not equal to other.

The != operator is synthesized from operator==.

(since C++20)

Parameters

other - another regex token iterator to compare to

Return value

1) true if *this is equal to other, false otherwise.

2) true if *this is not equal to other, false otherwise.
