Remarks

Channels that want to use the channel sink architecture must implement this interface on their ChannelData object.

Properties

ChannelUris	Gets an array of channel URIs to which the current channel maps.
Item[Object]	Gets or sets the data object associated with the specified key for the implementing channel.
