std::error_category
 
Defined in header <system_error>
class error_category;
(dal C++11)
std::error_category funge da classe base per i tipi specifici di categoria errore, ad esempio std::system_category, std::iostream_category, ecc Ogni classe specifica categoria definisce il error_code - mappatura error_condition e tiene i cordoni della esplicative per tutti error_conditions. Gli oggetti delle classi categoria di errore sono trattati come singleton, passato per riferimento.
Original:
