|ConnectionHandler||The default implementation of the ConnectionHandlerInterface.|
|ConnectionHandlerFactory||The default implementation of the ConnectionHandlerFactoryInterface.|
Objects implementing the ConnectionHandlerFactoryInterface can be used by the ConnectionPool to create handlers for new incoming connections.
Objects implementing the connection handler interface are usually instantiated via some method with an incoming connection and a kernel. The handler is notified when these connections are ready to be read or closed and should handle communication between the incoming connection and the kernel.
