Detailed Description

Event Oriented Classes

Objects contained within this namespace are responsible for dispatching signals.

All RTXI plugins and managers use the event system to communicate with each other. The RT::System also uses the event system to change it's own state, although it internally changes the format to account for transmitting information to the real-time thread.
