Registers which events the object would like to monitor. This ensures the code placed in the <OnEvent> section is not called for any unneccessary events such as an incoming chat message when your addon is only looking to perform actions based upon the start of casting a spell. The last frame to register for an event is the last one to receive it.

obj:RegisterEvent(event);
