This header is part of the regular expressions library.
Namespace std::regex_constants
Types | |
| Defined in namespace std::regex_constants | |
|---|---|
| (C++11) | general options controlling regex behavior (typedef) |

| (C++11) | describes different types of matching errors (typedef) |
Classes
| (C++11) | regular expression object (class template) |
| (C++11) | identifies the sequence of characters matched by a sub-expression (class template) |
| (C++11) | identifies one regular expression match, including all sub-expression matches (class template) |
| (C++11) | iterates through all regex matches within a character sequence (class template) |
| (C++11) | iterates through the specified sub-expressions within all regex matches in a given string or through unmatched substrings (class template) |
| (C++11) | reports errors generated by the regular expressions library (class) |
| (C++11) | provides metainformation about a character type, required by the regex library (class template) |
Functions
Algorithm | |
| (C++11) | attempts to match a regular expression to an entire character sequence (function template) |
| (C++11) | attempts to match a regular expression to any part of a character sequence (function template) |
| (C++11) | replaces occurrences of a regular expression with formatted replacement text (function template) |
Non-member operations | |
| (C++11) | specializes the std::swap algorithm (function template) |
compares two sub_match objects (function) | |
| outputs the matched character subsequence (function template) | |
| lexicographically compares the values in the two match result (function template) | |
