Parameter

• token
  Die vom Server erwartete verschlüsselte Autorisierungsmeldung.

• finished
  Der Abschlussstatus des Autorisierungsversuchs. true, wenn der Autorisierungsversuch abgeschlossen wurde, andernfalls false.

• connectionGroupId
  Ein eindeutiger Bezeichner, mit dem private Client-Server-Verbindungen erstellt werden können, die nur an dieses Authentifizierungsschema gebunden werden.

Beispiel

In diesem Codebeispiel wird eine neue Instanz der Authorization-Klasse mit der angegebenen Autorisierungsmeldung, dem angegebenen Abschlussstatus und dem angegebenen Bezeichner der Verbindungsgruppe erstellt.
