Expand description

ComponentAction Trait — Spec §5.2.2.4 (S. 20-21).

Spec-Zitat: “ComponentAction interface provides callbacks corresponding to the execution of the lifecycle operations of LightweightRTObject and ExecutionContext.”

Default-Implementations geben ReturnCode::Ok zurueck — Anwender implementieren nur die Callbacks, die fuer ihre Domaene relevant sind (Spec §5.2.2.4: “An RTC developer may implement these callback operations in order to execute application-specific logic”).
