Proprietà

ChannelScheme	Ottiene il tipo di listener al quale effettuare l'hook.
ChannelSinkChain	Ottiene la catena di sink del canale utilizzata dal canale corrente.
WantsToListen	Ottiene un valore Boolean che indica se è necessario eseguire l'hook dell'interfaccia IChannelReceiverHook al servizio di listener esterno.

Metodi

AddHookChannelUri(String)

Aggiunge un URI sul quale l'hook del canale resterà in attesa.
