Obtém a chave de classificação para a seqüência de caracteres
[first, last), de tal forma que se uma chave tipo compara a menos de outra chave de classificação com operator<, em seguida, a seqüência de caracteres que produziu a primeira chave de classificação vem antes da seqüência de caracteres que produziu a chave de classificação em segundo, no momento ordem local imbuído de agrupamento.Original:
Obtains the sort key for the character sequence

Por exemplo, quando a bandeira std::regex_constants::collate regex está definido, então a seqüência
[a-b] iria corresponder algum personagem c1 se traits.transform("a") <= traits.transform(c1) <= traits.transform("b"). Note que esta função tem uma seqüência de caracteres como argumento para acomodar as faixas definidas como [[.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.
