-/**
- * TErrorHandler class
- *
- * TErrorHandler handles all PHP user errors and exceptions generated during
- * servicing user requests. It displays these errors using different templates
- * and if possible, using languages preferred by the client user.
- * Note, PHP parsing errors cannot be caught and handled by TErrorHandler.
- *
- * The templates used to format the error output are stored under System.Exceptions.
- * You may choose to use your own templates, should you not like the templates
- * provided by Prado. Simply set {@link setErrorTemplatePath ErrorTemplatePath}
- * to the path (in namespace format) storing your own templates.
- *
- * There are two sets of templates, one for errors to be displayed to client users
- * (called external errors), one for errors to be displayed to system developers
- * (called internal errors). The template file name for the former is
- * <b>error[StatusCode][-LanguageCode].html</b>, and for the latter it is
- * <b>exception[-LanguageCode].html</b>, where StatusCode refers to response status
- * code (e.g. 404, 500) specified when {@link THttpException} is thrown,
- * and LanguageCode is the client user preferred language code (e.g. en, zh, de).
- * The templates <b>error.html</b> and <b>exception.html</b> are default ones
- * that are used if no other appropriate templates are available.
- * Note, these templates are not Prado control templates. They are simply
- * html files with keywords (e.g. %%ErrorMessage%%, %%Version%%)
- * to be replaced with the corresponding information.
- *
- * By default, TErrorHandler is registered with {@link TApplication} as the
- * error handler module. It can be accessed via {@link TApplication::getErrorHandler()}.
- * You seldom need to deal with the error handler directly. It is mainly used
- * by the application object to handle errors.
- *
- * TErrorHandler may be configured in application configuration file as follows
- * <module id="error" class="TErrorHandler" ErrorTemplatePath="System.Exceptions" />
- *
- * @author Qiang Xue <qiang.xue@gmail.com>
- * @version $Id$
- * @package System.Exceptions
- * @since 3.0
