Comentários

Números mais altos indicam prioridade mais alta, portanto, um canal com prioridade 50 tem uma prioridade maior do que um canal com prioridade 25. O canal de domínio entre aplicativos tem uma prioridade de 100.

Os canais cliente com prioridade mais alta têm a primeira chance de se conectar a um objeto remoto especificado por uma URL ou uma entrada de dados de canal específica de um ObjRef.

Para canais de servidor, a prioridade indica a ordem na qual seus dados de canal serão exibidos em um ObjRef, o que, por sua vez, afeta a ordem na qual os clientes tentarão se conectar ao objeto do servidor. Se o servidor estiver escutando em um canal HTTP com prioridade 50 e um canal TCP com prioridade 25 e o cliente tiver registrado um canal HTTP e TCP, o cliente usará o canal HTTP para falar com o servidor.
