Detailed Description

template<typename T, typename = typename std::enable_if<is_derived_from<T, ILocale>::value>::type>
class I18n< T, typename >

Internationalization manager for a specific locale type.

Handles the registration of supported locales, selection of the current locale, and retrieval of localized data at runtime. Implements a singleton pattern so there is only one instance per template type.

Template Parameters

T	is the base locale interface derived from ILocale, all supported locales must derive from

Handles the registration of supported locales, selection of the current locale, and retrieval of localized data at runtime. Implements a singleton pattern so there is only one instance per template type.

Template Parameters

T	The base locale interface type that all supported locales must derive from.

Parameters

code	Two-letter language code (e.g., "en", "fr").

Returns
