Template:cpp/regex/match results/sidebar

Defined in header <regex>
template<

    class BidirectionalIterator,
    class Allocator = std::allocator<std::sub_match<BidirectionalIterator>>

> class match_results;
 (since C++11)

The class template std::match_results holds a collection of character sequences that represent the result of a regular expression match.

This is a specialized allocator-aware container. It can only be default created or modified by passing to the std::regex_search() or std::regex_match() algorithms.

The first sub_match (index 0) contained in a match_result always represents the full match within a target sequence made by a regex, and subsequent sub_matches represent sub-expression matches corresponding in sequence to the left parenthesis delimiting the sub-expression in the regex.

Several specializations for common character sequence types are provided:

Template:tdcl list begin Template:tdcl list header Template:tdcl list hitem Template:tdcl list item Template:tdcl list item Template:tdcl list item Template:tdcl list item Template:tdcl list end
