-/**

- * This exception class and its children must only be used when

- * cache directory is not writable for instance).
- *
- * To help debugging template issues, this class tracks the original template
- * name and line where the error occurred.
- *
- * Whenever possible, you must set these information (original template name
- * and line number) yourself by passing them to the constructor. If some or all
- * these information are not available from where you throw the exception, then
- * this class will guess them automatically (when the line number is set to -1
- * and/or the filename is set to null). As this is a costly operation, this
- * can be disabled by passing false for both the filename and the line number
- * when creating a new instance of this class.
