Compare two strings.
This function compares two strings and returns the result by calling collate::do_compare().
lo1 | Start of string 1. | |
hi1 | End of string 1. | |
lo2 | Start of string 2. | |
hi2 | End of string 2. |

) | const [inline, inherited] |
Transform string to comparable form.
This function is a wrapper for strxfrm functionality. It takes the input string and returns a modified string that can be directly compared to other transformed strings. In the "C" locale, this function just returns a copy of the input string. In some other locales, it may replace two chars with one, change a char for another, etc. It does so by returning collate::do_transform().
lo | Start of string. | |
hi | End of string. |

long std::collate< CharT >::hash | ( | const CharT * | __lo, | |

) | const [inline, inherited] |
Return hash of a string.
This function computes and returns a hash on the input string. It does so by returning collate::do_hash().
lo | Start of string. | |
hi | End of string. |

Compare two strings.
This function is a hook for derived classes to change the value returned.
