Interface ILogNode


public interface ILogNode
A LogNode (a.k.a. Message Channel) represents a Node in the Publish/Subscribe logging system, that publishes messages to its subscribers.

The LogNode implements quite a lot of convenience-functions, for logging. Input gets wrapped in a LogMessage object inside the Node.
