Interface IndexedFeatureInfo

All Superinterfaces:

RefAssociation, RefBaseObject

All Known Implementing Classes:

IndexedFeatureInfo$Hib

public interface IndexedFeatureInfo
extends RefAssociation

IndexedFeatureInfo association proxy interface. The IndexedFeatureInfo association connects an Index instance to information about how the StructuralFeature instances that are constituents of the Index?s key are used by the Index.

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(CwmIndex index, CwmIndexedFeature indexedFeature) Creates a link between the pair of instance objects in the associations link set.
boolean	exists(CwmIndex index, CwmIndexedFeature indexedFeature) Queries whether a link currently exists between a given pair of instance objects in the associations link set.
CwmIndex	getIndex(CwmIndexedFeature indexedFeature) Queries the instance object that is related to a particular instance object by a link in the current associations link set.
List<CwmIndexedFeature>	getIndexedFeature(CwmIndex index) Queries the instance objects that are related to a particular instance object by a link in the current associations link set.
boolean	remove(CwmIndex index, CwmIndexedFeature indexedFeature) Removes a link between a pair of instance objects in the current associations link set.

Method Detail

exists

boolean exists(CwmIndex index,
               CwmIndexedFeature indexedFeature)

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

Parameters:

index - Value of the first association end.

indexedFeature - Value of the second association end.

Returns:

Returns true if the queried link exists.

getIndex

CwmIndex getIndex(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

List<CwmIndexedFeature> getIndexedFeature(CwmIndex index)

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

Parameters:

index - Required value of the first association end.

Returns:

List of related objects.

add

boolean add(CwmIndex index,
            CwmIndexedFeature indexedFeature)

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

Parameters:

index - Value of the first association end.

indexedFeature - Value of the second association end.

remove

boolean remove(CwmIndex index,
               CwmIndexedFeature indexedFeature)

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

Parameters:

index - Value of the first association end.

indexedFeature - Value of the second association end.
