Commenti

I numeri più alti indicano una priorità più alta, quindi un canale con priorità 50 ha una priorità più alta rispetto a un canale con priorità 25. Il canale tra domini dell'applicazione ha una priorità pari a 100.

Ai canali client con priorità più alta viene data la prima possibilità di connettersi a un oggetto remoto specificato da un URL o da una particolare voce di dati del canale da un oggetto ObjRef.

Per i canali server, la priorità indica l'ordine in cui i dati del canale verranno visualizzati in un ObjRefoggetto , che a sua volta influisce sull'ordine in cui i client tenteranno di connettersi all'oggetto server. Se il server è in ascolto su un canale HTTP con priorità 50 e un canale TCP con priorità 25 e il client ha registrato sia un canale HTTP che TCP, il client userà il canale HTTP per comunicare con il server.
