Methods

classmethod %Exists(oid As %ObjectIdentity) as %Boolean
Inherited description: 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
Inherited description: 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
Inherited description: 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 %Library.CacheStorage or %Library.CacheSQLStorage.
classmethod OnDeleteIsValid(val As %String) as %Status
classmethod OnUpdateIsValid(val As %String) as %Status
classmethod parentOnDelete(id As %String, concurrency As %Integer) as %Status
