Defined in header <locale>
template< class CharT > class messages;

Class template std::messages is a standard locale facet that encapsulates retrieval of strings from message catalogs, such as the ones provided by GNU catgets.

The source of the messages is implementation-defined.

Specializations

The standard library is guaranteed to provide the following specializations (they are required to be implemented by any locale object):

Defined in header <locale>
std::messages<char>	accesses narrow string message catalog
std::messages<wchar_t>	accesses wide string message catalog

Nested types

Type	Definition
char_type	CharT
string_type	std::basic_string<CharT>

Data members

Member	Description
std::locale::id id [static]	the identifier of the facet

Member functions

(constructor)	constructs a new messages facet (public member function)
(destructor)	destructs a messages facet (protected member function)
open	invokes do_open (public member function)
get	invokes do_get (public member function)
close	invokes do_close (public member function)

Protected member functions

do_open [virtual]	opens a named message catalog (virtual protected member function)
do_get [virtual]	retrieves a message from an open message catalog (virtual protected member function)
do_close [virtual]	closes a message catalog (virtual protected member function)

Inherited from std::messages_base

Nested types

Type	Definition
catalog	an unspecified signed integer type

See also

messages_base	defines messages catalog type (class)
messages_byname	represents the system-supplied std::messages for the named locale (class template)
