Class I18nPoolFactory

java.lang.Object

js.util.I18nPoolFactory

final class I18nPoolFactory
extends Object

Internal factory for I18nPool instances. This class provides a single factory method, see getInstance(boolean), that creates the actual instances. Support for multiple locale can be missing in which case this factory creates a simplified, optimized I18N pool instance. In this case locale is not used and all implemented methods silently ignore locale argument, if provided.

 I18nPool<Template> pool = I18nPoolFactory.getInstance(false); // I18N pool without multiple locale support
 pool.put("index.htm", new Template("index"), Locale.getDefault()); // locale is silently ignored
 

For I18N pool with multiple locale support returned instance is actually a map of maps. Outer map uses locale language tag for key while inner map uses object name. For instances with multiple locale support, locale argument is mandatory and all implemented methods throw illegal arguments exception if locale is missing.

 I18nPool<Template> pool = I18nPoolFactory.getInstance(true); // I18N pool with multiple locale support
 pool.put("index.htm", new Template("index")); // missing locale rise illegal argument exception

Method Detail

getInstance

public static <T> I18nPool<T> getInstance(boolean multiLocale)

Create new I18N pool instance. If multiple locale support is not requested this factory creates a simplified, optimized I18N pool instance. In this case, if optional locale parameter is provided, it is silently ignored, see I18nPool interface.

For I18N pool with multiple locale support returned instance is actually a map of maps. Outer map uses locale language tag for key while inner map uses object name.

Type Parameters:

T - instance type.

Parameters:

multiLocale - flag for multiple locale support.

Returns:

new I18N pool instance.
