31.12 Regular expression iterators [re.iter]

31.12.2 Class template regex_­token_­iterator [re.tokiter]

31.12.2.4 regex_­token_­iterator increment [re.tokiter.incr]

regex_token_iterator& operator++();

1
#

Effects: Constructs a local variable prev of type position_­iterator, initialized with the value of position.

2
#

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

3
#

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

4
#

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.

5
#

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).

6
#

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

7
#

Returns: *this

regex_token_iterator& operator++(int);

8
#

Effects: Constructs a copy tmp of *this, then calls ++(*this).

9
#

Returns: tmp.
