std::regex_token_iterator::operator==,operator!=(3) C++ Standard Libary std::regex_token_iterator::operator==,operator!=(3)

NAME

std::regex_token_iterator::operator==,operator!= - std::regex_token_iterator::operator==,operator!=

Synopsis


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)


This section is incomplete
Reason: Explain better. For example, subs is an exposition-only vector of matched
sub-expressions.

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.
