std::locale::facet(3) C++ Standard Libary std::locale::facet(3) NAME std::locale::facet - std::locale::facet Synopsis Defined in header <locale> class locale::facet; std::locale::facet is the base class for facets. It provides a com- mon base class so that locales could store pointers to the facets they implement in a single indexed container, and it abstracts support for facet reference counting. Whenever a facet is added to a locale, the locale increments the reference count in the facet (through an implementation-specific mechanism). Whenever a locale is destructed or modified, it decrements the reference count in each facet it no longer implements. Whenever a facet's reference count becomes zero, the lo- cale performs delete static_cast<std::locale::facet*>(f); where f is the pointer to the facet. Member functions constructor constructs a new facet with specified reference count (protected member function) operator= the copy assignment operator is deleted (protected member function) destructor the destructor is protected virtual [virtual] (virtual protected member function) Example This section is incomplete Reason: no example Defect reports The following behavior-changing defect reports were applied retroac- tively to previously published C++ standards. DR Applied to Behavior as published Correct behavior LWG 2694 C++98 the definition of 'facet' was removed by added the definition the resolution of LWG issue 436 back See also the facet index type: each facet class must declare or inherit a public static id member of this type (class) Category: * Todo no example http://cppreference.com 2024.06.10 std::locale::facet(3)
