template<typename _Bi_iter, typename _Allocator = allocator<sub_match<_Bi_iter> >> allocator_type std::match_results< _Bi_iter, _Allocator >::get_allocator () const [inline]¶
Gets a copy of the allocator. Definition at line 1807 of file regex.h.template<typename _Bi_iter, typename _Allocator = allocator<sub_match<_Bi_iter> >> difference_type std::match_results< _Bi_iter, _Allocator >::length (size_type__sub = 0) const [inline]¶
Gets the length of the indicated submatch. Parameters:sub indicates the submatch.
Precondition:
ready() == true
This function returns the length of the indicated submatch, or the length of the
entire match if sub is zero (the default).

template<typename _Bi_iter, typename _Allocator = allocator<sub_match<_Bi_iter> >> size_type std::match_results< _Bi_iter, _Allocator >::max_size () const [inline]¶
Gets the number of matches and submatches. The number of matches for a given regular expression will be either 0 if there was no match or mark_count() + 1 if a match was successful. Some matches may be empty. Returns:the number of matches found.
template<typename _Bi_iter, typename _Allocator = allocator<sub_match<_Bi_iter> >> match_results& std::match_results< _Bi_iter, _Allocator >::operator= (const match_results< _Bi_iter, _Allocator > &__rhs) [inline]¶

Gets a sub_match reference for the match or submatch. Parameters:sub indicates the submatch.
Precondition:
ready() == true
This function gets a reference to the indicated submatch, or the entire match if
sub is zero.
If sub >= size() then this function returns a sub_match with a special
value indicating no submatch.

template<typename _Bi_iter, typename _Allocator = allocator<sub_match<_Bi_iter> >> difference_type std::match_results< _Bi_iter, _Allocator >::position (size_type__sub = 0) const [inline]¶
Gets the offset of the beginning of the indicated submatch. Parameters:sub indicates the submatch.
Precondition:
ready() == true
This function returns the offset from the beginning of the target sequence to
the beginning of the submatch, unless the value of sub is zero (the default),
in which case this function returns the offset from the beginning of the
target sequence to the beginning of the match.
Returns -1 if sub is out of range.

template<typename _Bi_iter, typename _Allocator = allocator<sub_match<_Bi_iter> >> const_reference std::match_results< _Bi_iter, _Allocator >::prefix () const [inline]¶
Gets a sub_match representing the match prefix. Precondition:ready() == true
This function gets a reference to a sub_match object representing the part of
the target range between the start of the target range and the start of the
match.

result state.
false The object is not ready.
template<typename _Bi_iter, typename _Allocator = allocator<sub_match<_Bi_iter> >> size_type std::match_results< _Bi_iter, _Allocator >::size () const [inline]¶
Gets the number of matches and submatches. The number of matches for a given regular expression will be either 0 if there was no match or mark_count() + 1 if a match was successful. Some matches may be empty. Returns:the number of matches found.
template<typename _Bi_iter, typename _Allocator = allocator<sub_match<_Bi_iter> >> string_type std::match_results< _Bi_iter, _Allocator >::str (size_type__sub = 0) const [inline]¶
Gets the match or submatch converted to a string type. Parameters:sub indicates the submatch.
Precondition:
ready() == true
This function gets the submatch (or match, if sub is zero) extracted from the
target range and converted to the associated string type.
