OIL2 Class Standard.ShutdownService

class Standard . ShutdownService {
        set     shutdownList;
        oid     shutdownObj;
} inherits from Object;

DESCRIPTION

Class ShutdownService provides a facility by which objects residing within an FARGOS/VISTA Object Management Environment can be notified of an impending system shutdown. One and only one object of this class will be instantiated within a given address space. This creation is done automatically by the boot process of a FARGOS/VISTA Object Management Environment daemon.

The object Id is registered as the local service "ShutdownService", which is implicitly defined by the constant SHUTDOWN_SERVICE_NAME in the standard OIL2 header file OMEcore.o2h.

Standard.ShutdownService:removeNotifyOnShutdown
