The common +attributes (indeed not CORBA attributes, they're state members) like +creation time and id of the origin are in a base class. Concrete +events like Temperature, Position and Log Message are derived from +this class. + +The client sends a few random events to the server. The server has +suitable implementations of the event classes. So it is able to show +the incoming events by invoking the do_print () operation, which is +declared in the Event baseclass. After that the server does an +"alarm" check on the event. For each possible origin id (KITCHEN, +BATHROOM) a criterion has been registered. The criterion which equals +the origin id of the event is searched and then asked with is_critical +(event). + +Finally a list with all the events which causes an alarm is requested +by the client. + +Start with: + +% ./server -o ior +% ./client -f ior [-x] + + |
