| | | | | ----------------------- | | | | protected: ~codecvt(); | | |

Destructs a std::codecvt facet. This destructor is protected and virtual (due to base class destructor being virtual). An object of type std::codecvt, like most facets, can only be destroyed when the last std::locale object that implements this facet goes out of scope or if a user-defined class is derived from std::codecvt and implements a public destructor.

[edit] Example

#include #include struct Destructible_codecvt : public std::codecvt<wchar_t, char, std::mbstate_t> { Destructible_codecvt(std::size_t refs = 0) : codecvt(refs) {} // note: the implicit destructor is public }; int main() { Destructible_codecvt dc; // std::codecvt c; // compile error: protected destructor }
