CosTimerEvent_TimerEventService(3erl) Erlang Module Definition CosTimerEvent_TimerEventService(3erl)NAME
CosTimerEvent_TimerEventService - This module implements the OMG CosTimerEvent::TimerEventService interface.
DESCRIPTION
To get access to the record definitions for the structures use:
-include_lib("cosTime/include/*.hrl").
EXPORTS
register(TimerEventService, CosEventCommPushConsumer, Data) -> TimerEventHandler
Types TimerEventService = CosEventCommPushConsumer = TimerEventHandler = #objref
Data = #any
This operation will create a new TimerEventHandler object which will push given Data to given CosEventCommPushConsumer after the
timer have been set.
unregister(TimerEventService, TimerEventHandler) -> ok
Types TimerEventService = TimerEventHandler = #objref
This operation will terminate the given TimerEventHandler.
event_time(TimerEventService, TimerEvent) -> UTO
Types TimerEventService = #objref
TimerEvent = #'CosTimerEvent_TimerEvent'{utc, event_data}
utc =
event_data = #any}
UTO = #objref
This operation returns a UTO containing the time at which the associated event was triggered.

cosTime(3erl) Erlang Module Definition cosTime(3erl)NAME
cosTime - The main module of the cosTime application
DESCRIPTION
To get access to the record definitions for the structures use:
-include_lib("cosTime/include/*.hrl").
This module contains the functions for starting and stopping the application.
This application use the time base 15 october 1582 00:00 . Performing operations using other time bases will not yield correct result.
The OMG CosTime specification defines the operation secure_universal_time . As of today we cannot provide this functionality considering
the criteria demanded to fulfill the OMG specification.
When using this application, time and inaccuracy supplied by the user must be given in number of 100 nano seconds . The Time Displacement
Factor is positive east of the meridian, while those to the west are negative.
This application use calender:now_to_universal_time(Now) to create a UTC. Hence, the underlying OS must deliver a correct result when call-
ing erlang:now() .
When determining the inaccuracy of the system, the user should consider the way the time objects will be used. Communicating with other
ORB's, add a substantial overhead and should be taken into consideration.
EXPORTS
install_time() -> Return
Types Return = ok | {'EXIT', Reason}
This operation installs the cosTime Time Service part application.
uninstall_time() -> Return
Types Return = ok | {'EXIT', Reason}
This operation uninstalls the cosTime Time Service part application.
install_timerevent() -> Return
Types Return = ok | {'EXIT', Reason}
This operation installs the cosTime Timer Event Service part application.
Note:
The Timer Event Service part requires Time Service part and cosEvent or the cosNotification application to be installed first.
uninstall_timerevent() -> Return
Types Return = ok | {'EXIT', Reason}
This operation uninstalls the cosTime Timer Event Service part application.
start() -> Return
Types Return = ok | {error, Reason}
This operation starts the cosTime application.
stop() -> Return
Types Return = ok | {error, Reason}
This operation stops the cosTime application.
start_time_service(Tdf, Inaccuracy) -> Return
Types Tdf = short()
Inaccuracy = ulonglong(), eq. #100 nano seconds
Return = ok | {'EXCEPTION', #'BAD_PARAM'{}}
This operation starts a Time Service server. Please note that there may only be exactly one Time Service active at a time. The Inac-
curacy parameter defines the inaccuracy the underlying OS will introduce. Remember to take into account latency when passing time
object between nodes.
stop_time_service(TimeService) -> ok
Types TimeService = #objref
This operation stops the Time Service object.
start_timerevent_service(TimeService) -> ok
Types TimeService = #objref
This operation starts a Timer Event Service server. Please note that there may only be exactly one Timer Event Service per node
active at a time. The supplied TimeServcie reference will be the object Timer Event Service contacts to get access to a new UTC.
stop_timerevent_service(TimerEventService) -> ok
Types TimerEventService = #objref
This operation stops the Timer Event Service object.
