Chain of Responsibility

Chain of Responsibility pattern passes a request into a chain of objects - each object processes the request and decides whether to pass to the next object.

Code

Logger is an abstract class implemented by ConsoleLogger, FileLogger, and EmailLogger. Logger provides AddNext() to chain another Logger. When the caller calls Log(), the logger writes log and asks the next logger does the same if needed.
