46
 * Automatically add requested strings
47

48
 * This Decorator will add strings to a language when a request for them to be
49
 * translated happens. The 'autoaddlang' option must be set to the language the
50
 * strings will be added as.
51
 *
52
 * Example:
53
 * <pre>
54
 * $tr =& Translation2_Admin::factory(...);
55
 * $tr->setLang('en');
56
 * $tr =& $tr->getAdminDecorator('Autoadd');
57
 * $tr->setOption('autoaddlang', 'en');
58
 * ...
59
 * $tr->get('Entirely new string', 'samplePage', 'de');
60
 * </pre>
61
 *
62
 * 'Entirely new string' will be added to the English language table.
