Detailed Description

Class definition of EventLoopMgr.

This is the default processing manager of the application manager. This object handles the minimal requirements needed by the application manager. It also handles the default user configuration setup for standard event processing.

  • handling of the incidents when starting event processing
  • handling of the event loop
