• classmethod %Exists(oid As %ObjectIdentity)
as %Boolean
Checks to see if the object identified by the OID oid exists in the extent.
Returns %Boolean TRUE if it exists, FALSE if it does not.
• 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 %Storage.Persistent or %Storage.SQL.
• 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. If this method is not overridden
then the default implementation returns an error. This method is normally generated by
the storage class for persistent classes using %Storage.Persistent or %Storage.SQL.
