NAME

 
facets
 
 - A family of classes used to encapsulate categories of locale functionality.
 
 
 

DESCRIPTION

 
 
The Standard C++ Localization library includes a locale interface that contains a collection of diverse facets. Each facet has localization facilities for some specific area, such as character classification or numeric formatting. Each facet also falls into one or more broad categories. These categories are defined in the locale class, and the standard facets fit into these categories as follows.
 
CATEGORYFACETS
 
 
collatecollate, collate_byname
 
ctypectype, codecvt, ctype_byname, codecvt_byname
 
monetarymoneypunct, moneypunct_byname, money_put, money_get
 
numericnumpunct, numpunct_byname, num_put, num_get
 
timetime_put, time_put_byname, time_get, time_get_byname
 
messagesmessages, messages_byname
 
 
 
A facet must satisfy two properties. First, it must be derived from the base class locale::facet, either directly or indirectly (for example, facet -> ctype<char> -> my_ctype). Second, it must contain a member of type locale::id. This ensures that the locale class can manage its collection of facets properly.
