Par exemple, lorsque le drapeau std::regex_constants::collate regex est définie, alors la séquence
[a-b] correspondrait à un certain caractère c1 si traits.transform("a")<= traits.transform(c1)<= traits.transform("b"). Notez que cette fonction prend une chaîne de caractères comme argument pour accueillir les plages définies comme [[.ae.]-d] .Original:
For example when the regex flag std::regex_constants::collate is set, then the sequence
[a-b] would match some character c1 if traits.transform("a")<= traits.transform(c1)<= traits.transform("b"). Note that this function takes a character sequence as the argument to accomodate to the ranges defined like [[.ae.]-d].The text has been machine-translated via Google Translate.
