Detailed Description

Functor to translate language names into language constants.

::OKlib::Messages::LanguageName(name), where name is a C-string, yields a value of type OKlib::Messages::Languages (an enumeration type), while throwing an exception of type LanguageName::UninterpretableLanguageName in case name doesn't refer to an existing language.

The available names are exactly the names of the enumerated constants in the enumeration type OKlib::Messages::Languages (so LanguageName(name) is just the value of name as C++ constant), which in turn are exactly the strings given by the macro OKLIB_LANGUAGES (in OKlib/Programming/Messages/Languages.hpp). Since the language names are made available by the array OKlib::Messages::Locales, class LanguageName is nothing than a find-wrapper for this array (enabling faster access than by just linearly searching through this array).

For example LanguageName("en_GB") == ::OKlib::Messages::en_GB == ::OKlib::Messages::Languages(0).
