DESCRIPTION

CNEventExploder is a subclass derived from CNEventHandler.
It maintains a list of other arbitrary CNEventHandlers and forwards all received events to all the CNEventHandlers in its list. This can be used to implement "broadcast"-events.

Constructors:

CNEventExploder();

CNEventExploder(CNParam *param);

Initializes the event exploder.

In addition to the member functions required by CNCL, CNEventExploder provides the following member functions:

virtual void event_handler(const CNEvent *ev);

This function receives an event and re-sends it to other CNEventHandlers.

virtual void add_handler(CNEventHandler *eh);

This function adds a new CNEventHandler to the list. It will then receive all events that are send to the CNEventExploder. If a CNEventHandler is added more than once, it will also receive all events as many times.

virtual void rem_handler(CNEventHandler *eh);

This function removes a previously added CNEventHandler from the list. It will no longer receive events managed by the CNEventExploder. If a CNEventHandler has been added more than once, it also has to be removed as many times to be completely removed from the CNEventExploder.
