       CosTimerEvent_TimerEventHandler      -      This     module     implements     the     OMG
       CosTimerEvent::TimerEventHandler interface.


       To get access to the record definitions for the structures use:


       '_get_status'(TimerEventHandler) -> Reply


                 TimerEventHandler = #objref
                 Reply = 'ESTimeSet' | 'ESTimeCleared' | 'ESTriggered' | 'ESFailedTrigger'

              This operation returns the status of the target object.

                * 'ESTimeSet' - timer is set to trigger event(s).

                * 'ESTimeCleared' - no time set or the timer have been reset.

                * 'ESTriggered' - event has already been sent.

                * 'ESFailedTrigger' - tried to, but failed, sending the event.

              If the target object is of type 'TTPeriodic' the status value 'ESTriggered' is  not

       time_set(TimerEventHandler) -> Reply


                 TimerEventHandler = #objref
                 Reply = {boolean(), UTO}
                 UTO = #objref

              This operation returns true if the time has been set for an event that is yet to be
              triggered, false otherwise. The outparameter represents the current time  value  of
              the target object.

       set_timer(TimerEventHandler, TimeType, TriggerTime) -> void()


                 TimerEventHandler = #objref
                 TimeType = 'TTAbsolute' | 'TTRelative' | 'TTPeriodic'
                 TriggerTime = UTO
                 UTO = #objref

              This operation terminates any previous set trigger, and set a new trigger specified
              by the TimeType and UTO objects.

              The relation between the UTO object and the TimeTypes are:

                * 'TTAbsolute' - the UTO object must represent absolute time, i.e., number of 100
                  nanoseconds passed since 15 october 1582 00:00.

                * 'TTRelative'  - the UTO object must represent the from now until when the event
                  should be triggered, e.g., within 30*10^7 nanoseconds.

                * 'TTPeriodic' - the same as for 'TTRelative', but this option  will  trigger  an
                  event periodically until timer cancelled.

       cancel_timer(TimerEventHandler) -> boolean()


                 TimerEventHandler = #objref

              This  operation cancel, if possible, the triggering of event(s). Returns true if an
              event is actually cancelled, false otherwise.

       set_data(TimerEventHandler, EventData) -> ok


                 TimerEventHandler = #objref
                 EventData = #any

              This operation changes the event data sent when triggered.
