This decorator is very useful when you want to provide a fallback language
for empty strings. It is stackable, so you can have more than one default language.
Use setOption() with the fallbackLang
parameter to specify the fallback language of the current decorator.
<?php
$tr = new Translation2($driver, $dbinfo, $params);
//set English as the main language
$tr->setLang('en');
//set Italian as the first fallback language
$tr =& $tr->getDecorator('Lang');
$tr->setOption('fallbackLang', 'it');
//set Spanish as the second fallback language
$tr =& $tr->getDecorator('Lang');
$tr->setOption('fallbackLang', 'es');
?>
