| The event handler that is decorated by this class.

## Detailed Description

This class is the Decorator Pattern Base class for decorating ACE_Event_Handler.

It simply forwards the requests for get_handle (), handle_input () and handle_qos () to its event_handler_ component. Concrete decorators for ACE_Event_Handler will use this class to access the basic event handler functionality and decorate that by their own implementation.
