• classmethod %LockId(id As %String, shared As %Boolean = 0, timeout As %Integer) as %Status
Obtain an exclusive or shared lock on the object identified by id. The type of lock obtained is determined by shared. This method is normally generated by the storage class for persistent classes using %Library.CacheStorage or %Library.CacheSQLStorage.
• classmethod %UnlockId(id As %String, shared As %Boolean = 0, immediate As %Boolean = 0) as %Status
Release an exclusive or shared lock on the object identified by id. The type of lock released is determined by shared.
