Detailed Description

template<typename _Bi_iter, typename _Alloc = allocator<sub_match<_Bi_iter> >>
class std::match_results< _Bi_iter, _Alloc >

The results of a match or search operation.

A collection of character sequences representing the result of a regular expression match. Storage for the collection is allocated and freed as necessary by the member functions of class template match_results.

This class satisfies the Sequence requirements, with the exception that only the operations defined for a const-qualified Sequence are supported.

The sub_match object stored at index 0 represents sub-expression 0, i.e. the whole match. In this case the sub_match member matched is always true. The sub_match object stored at index n denotes what matched the marked sub-expression n within the matched expression. If the sub-expression n participated in a regular expression match then the sub_match member matched evaluates to true, and members first and second denote the range of characters [first, second) which formed that match. Otherwise matched is false, and members first and second point to the end of the sequence that was searched.
