Interface UniqueFeature

All Superinterfaces:

RefAssociation, RefBaseObject

All Known Implementing Classes:

UniqueFeature$Hib

public interface UniqueFeature
extends RefAssociation

UniqueFeature association proxy interface. The UniqueFeature association identifies the Feature instances of a Class instance that confer uniqueness. The ordered constraint is used to determine the order of StructuralFeature instances in the UniqueKey instance.

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(CwmStructuralFeature feature, CwmUniqueKey uniqueKey) Creates a link between the pair of instance objects in the associations link set.
boolean	exists(CwmStructuralFeature feature, CwmUniqueKey uniqueKey) Queries whether a link currently exists between a given pair of instance objects in the associations link set.
List<CwmStructuralFeature>	getFeature(CwmUniqueKey uniqueKey) Queries the instance objects that are related to a particular instance object by a link in the current associations link set.
Collection<CwmUniqueKey>	getUniqueKey(CwmStructuralFeature feature) Queries the instance objects that are related to a particular instance object by a link in the current associations link set.
boolean	remove(CwmStructuralFeature feature, CwmUniqueKey uniqueKey) Removes a link between a pair of instance objects in the current associations link set.

Method Detail

exists

boolean exists(CwmStructuralFeature feature,
               CwmUniqueKey uniqueKey)

Queries whether a link currently exists between a given pair of instance objects in the associations link set.

Parameters:

feature - Value of the first association end.

uniqueKey - Value of the second association end.

Returns:

Returns true if the queried link exists.

getFeature

List<CwmStructuralFeature> getFeature(CwmUniqueKey uniqueKey)

Queries the instance objects that are related to a particular instance object by a link in the current associations link set.

Parameters:

uniqueKey - Required value of the second association end.

Returns:

List of related objects.

getUniqueKey

Collection<CwmUniqueKey> getUniqueKey(CwmStructuralFeature feature)

Queries the instance objects that are related to a particular instance object by a link in the current associations link set.

Parameters:

feature - Required value of the first association end.

Returns:

Collection of related objects.

add

boolean add(CwmStructuralFeature feature,
            CwmUniqueKey uniqueKey)

Creates a link between the pair of instance objects in the associations link set.

Parameters:

feature - Value of the first association end.

uniqueKey - Value of the second association end.

remove

boolean remove(CwmStructuralFeature feature,
               CwmUniqueKey uniqueKey)

Removes a link between a pair of instance objects in the current associations link set.

Parameters:

feature - Value of the first association end.

uniqueKey - Value of the second association end.
