Comentários

Os canais que desejam usar a arquitetura do coletor de canal devem implementar essa interface em seu ChannelData objeto.

Propriedades

ChannelUris	Obtém uma matriz de URIs de canal para a qual o canal atual é mapeado.
Item[Object]	Obtém ou define o objeto de dados associado com a chave especificada para o canal de implementação.
