DBStorageGroupScan:
CEDAR
DEFINITIONS =
BEGIN
This is the interface to the group scan manager. Operations on individual scans
are located in DBStorage.
Init:
PROC;
Should be called from DBStorage.Initialize.
CheckState:
PROC[doPrinting:
BOOLEAN];
Checks lists of active and free group scans for validity. If doPrinting, also
prints these lists to IODefs.
CallAfterFinishTransaction:
PROC [];
Invalidates all active scans on Segments that are no longer addressible (because
transaction went away). Invalidation includes releasing tuples that are part of
the scan.
END.--DBStorageGroupScan
