All Superinterfaces:

RefAssociation, RefBaseObject

All Known Implementing Classes:

ObjectSlot$Hib

public interface ObjectSlot
extends RefAssociation

ObjectSlot association proxy interface. The ObjectSlot association connects Slot instances with their owning Object instances.

Note: This type should not be subclassed, implemented or directly instantiated by clients. It is generated from a MOF metamodel and implemented by Enki or MDR.

Method Summary

boolean	add(CwmSlot slot, CwmObject object) Creates a link between the pair of instance objects in the associations link set.
boolean	exists(CwmSlot slot, CwmObject object) Queries whether a link currently exists between a given pair of instance objects in the associations link set.
CwmObject	getObject(CwmSlot slot) Queries the instance object that is related to a particular instance object by a link in the current associations link set.
Collection<CwmSlot>	getSlot(CwmObject object) Queries the instance objects that are related to a particular instance object by a link in the current associations link set.
boolean	remove(CwmSlot slot, CwmObject object) Removes a link between a pair of instance objects in the current associations link set.
