IServerChannelSink Interface

'Declaration <ComVisibleAttribute(True)> _ Public Interface IServerChannelSink Inherits IChannelSinkBase 'Usage Dim instance As IServerChannelSink

ComVisibleAttribute(true) public interface IServerChannelSink extends IChannelSinkBase
Channel sinks provide a plug-in point that allows access to the underlying messages flowing through the channel as well as the stream used by the transport mechanism to send messages to a remote object. Channel sinks are linked together in a chain of channel sink providers, and all channel messages flow through this chain of sinks before the message is serialized and transported.
The following code example illustrates an implementation of the IServerChannelSink interface.
