Implémentations typiques de std::basic_stringbuf tenir un objet de type std::basic_string directement en tant que membre de données et l'utiliser à la fois la séquence de caractères contrôlée (le tableau où les six pointeurs de std::basic_streambuf sont pointant vers) et que la séquence de caractères associée (la source de caractères pour tous les opérations d'entrée et de la cible pour la sortie). En outre, une mise en oeuvre typique est titulaire d'un membre de données de type de std::ios_base::openmode pour indiquer l'état du cours d'eau (entrée uniquement, de sortie de sortie uniquement, ou entrée /) .
Original:
Typical implementations of std::basic_stringbuf hold an object of type std::basic_string directly as a data member and use it as both the controlled character sequence (the array where the six pointers of std::basic_streambuf are pointing to) and as the associated character sequence (the source of characters for all input operations and the target for the output). In addition, a typical implementation holds a data member of type std::ios_base::openmode to indicate the status of the stream (input-only, output-only, or input/output).
