Hinweise

Die empfangende Seite von Kanälen muss die IChannelReceiver Schnittstelle verfügbar machen.

Eigenschaften

ChannelData	Ruft die channelspezifischen Daten ab.
ChannelName	Ruft den Namen des Channels ab. (Geerbt von IChannel)
ChannelPriority	Ruft die Priorität des Channels ab. (Geerbt von IChannel)

Methoden

GetUrlsForUri(String)	Gibt ein Array aller URLs für einen URI zurück.
Parse(String, String)	Gibt den Objekt-URI als Out-Parameter und den URI des aktuellen Channels als Rückgabewert zurück. (Geerbt von IChannel)
StartListening(Object)	Weist den aktuellen Channel an, mit der Überwachung von Anforderungen zu beginnen.
StopListening(Object)	Weist den aktuellen Channel an, die Überwachung von Anforderungen zu beenden.
