getMessageObject()
Return a Message object for this exception.
The Message class provides methods which fulfil two basic services:
Definition: Message.php:162
__construct( $title, $msg, $params=[])
Note: these arguments are keys into wfMessage(), not text!
msg( $key, $fallback,... $params)
Get a message from i18n.
Definition: MWException.php:75
An error page which can definitely be safely rendered using the OutputPage.
$wgOut
Definition: Setup.php:862
wfMessage( $key,... $params)
This is the function for getting translated interface messages.
report( $action=self::SEND_OUTPUT)
Interface for MediaWiki-localized exceptions.
