Interface IndexedFeatures

All Superinterfaces:

RefAssociation, RefBaseObject

All Known Implementing Classes:

IndexedFeatures$Hib

public interface IndexedFeatures
extends RefAssociation

IndexedFeatures association proxy interface. The IndexedFeatures association links StructuralFeature instances to information about how they participate in the keys of Index 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(CwmStructuralFeature feature, CwmIndexedFeature indexedFeature) Creates a link between the pair of instance objects in the associations link set.
boolean	exists(CwmStructuralFeature feature, CwmIndexedFeature indexedFeature) Queries whether a link currently exists between a given pair of instance objects in the associations link set.
CwmStructuralFeature	getFeature(CwmIndexedFeature indexedFeature) Queries the instance object that is related to a particular instance object by a link in the current associations link set.
Collection<CwmIndexedFeature>	getIndexedFeature(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, CwmIndexedFeature indexedFeature) Removes a link between a pair of instance objects in the current associations link set.

Method Detail

exists

boolean exists(CwmStructuralFeature feature,
               CwmIndexedFeature indexedFeature)

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.

indexedFeature - Value of the second association end.

Returns:

Returns true if the queried link exists.

getFeature

CwmStructuralFeature getFeature(CwmIndexedFeature indexedFeature)

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

Parameters:

indexedFeature - Required value of the second association end.

Returns:

Related object or null if none exists.

getIndexedFeature

Collection<CwmIndexedFeature> getIndexedFeature(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,
            CwmIndexedFeature indexedFeature)

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

Parameters:

feature - Value of the first association end.

indexedFeature - Value of the second association end.

remove

boolean remove(CwmStructuralFeature feature,
               CwmIndexedFeature indexedFeature)

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

Parameters:

feature - Value of the first association end.

indexedFeature - Value of the second association end.
