Commenti

I canali che vogliono usare l'architettura del sink del canale devono implementare questa interfaccia nell'oggetto ChannelData .

Proprietà

ChannelUris	Ottiene una matrice di URI del canale associati al canale corrente.
Item[Object]	Ottiene o imposta l'oggetto dati associato alla chiave specificata per il canale di implementazione.
