Event Management Framework Quick Reference

SOMObject

SOMEEman

SOMEEMRegisterData

Class Organization

— Handles input events. EMan performs a blocked (or timed) wait

on all registered event sources concurrently.

— Holds registration information for event types to be registered with

the SOMEEman class.

SOMEEvent

— Timestamps an event before it is passed to a callback routine. This

is the base class for all generic events within the Event Manager.

SOMEClientEvent

— Describes generic client events within EMan. Client events are

defined created, processed, and destroyed entirely by the application.

SOMESinkEvent

— Describes a sink event generated by EMan when activity occurs on

a registered sink. EMan passes an instance of SOMESinkEvent to

the callback registered for sink events, so the callback can query it.

SOMETimerEvent

— Describes a timer event generated by EMan when a registered timer

pops. EMan passes an instance of SOMETimerEvent to the callback

registered for timer events, so the callback can query it.

SOMEWorkProcEvent

— Describes a work procedure event object generated by EMan

when a work procedure is registered and there are no other

events to process in EMan. EMan passes an instance of

SOMEWorkProcEvent to the callbacks of each registered

Work Procedure.

SOMEClientEvent class
