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

NAME

std::regex_token_iterator::operator++,operator++(int) - std::regex_token_iterator::operator++,operator++(int)

Synopsis


regex_token_iterator& operator++(); (since C++11)
regex_token_iterator operator++(int); (since C++11)


Advances the iterator on the next sub match.


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


If *this is a suffix iterator, sets *this to an end-of-sequence iterator.


Otherwise, if N + 1 < subs.size(), increments N and sets result to the address of
the current match.


Otherwise, sets N to 0 and increments position. If position is not an
end-of-sequence iterator the operator sets result to the address of the current
match.


Otherwise, if any of the values stored in subs is equal to -1 and
prev->suffix().length() is not 0 the operator sets *this to a suffix iterator
that points to the range [prev->suffix().first, prev->suffix().second).


Otherwise, sets *this to an end-of-sequence iterator.


The behavior is undefined if the iterator is end-of-sequence iterator.

Parameters


(none)

Return value


1) *this
2) The previous value of the iterator.
