Beispiel

Im folgenden Codebeispiel soll das Verhalten der ToXml-Methode veranschaulicht werden, auf ihre Verwendung wird jedoch nicht eingegangen. Im Allgemeinen werden die Methoden von Berechtigungsklassen durch die Sicherheitsinfrastruktur verwendet und sind nicht für die Verwendung in Anwendungen bestimmt. Im folgenden Codebeispiel wird jedoch veranschaulicht, wie sich die Methode verhält, wenn sie vom Code aus ausgeführt wird. Den vollständigen Beispielcode finden Sie in der SecurityPermission-Klasse.
