Container class for localization functionality.
The locale class is first a class wrapper for C library locales. It is also an extensible container for user-defined localization. A locale is a collection of facets that implement various localization features such as money, time, and number printing.
Constructing C++ locales does not change the C library locale.
This library supports efficient construction and copying of locales through a reference counting implementation of the locale class.

Named locale constructor.
Constructs a copy of the named C library locale.
s | Name of the locale to construct. |
std::runtime_error | if s is null or an undefined locale. |
Construct locale with facets from another locale.
Constructs a copy of the locale base. The facets specified by cat are replaced with those from the locale named by s. If base is named, this locale instance will also be named.
base | The locale to copy. | |
s | Name of the locale to use facets from. | |
cat | Set of categories defining the facets to use from s. |

Locale destructor.
Construct locale with another facet.
Constructs and returns a new copy of this locale. Adds or replaces an existing facet of type Facet from the locale other into the new locale.
std::runtime_error | if other has no facet of type Facet. |

Compare two strings according to collate.
Template operator to compare two strings using the compare function of the collate facet in this locale. One use is to provide the locale to the sort function. For example, a vector v of strings could be sorted according to locale loc by doing:
std::sort(v.begin(), v.end(), loc);
s1 | First string to compare. | |
s2 | Second string to compare. |

Category values.
The standard category values are none, ctype, numeric, collate, time, monetary, and messages. They form a bitmask that supports union and intersection. The category all is the union of these values.
