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.
