Hinweise

Kanalsenken bieten einen Plug-In-Punkt, der den Zugriff auf die zugrunde liegenden Nachrichten ermöglicht, die durch den Kanal fließen, sowie auf den Stream, der vom Transportmechanismus zum Senden von Nachrichten an ein Remoteobjekt verwendet wird. Kanalsenken werden in einer Kette von Kanalsenkenanbietern miteinander verknüpft, und alle Kanalnachrichten fließen durch diese Kette von Senken, bevor die Nachricht serialisiert und transportiert wird.
