Interface NestedLoopJoinHasLeftJoinKey

All Superinterfaces:

RefAssociation, RefBaseObject

All Known Implementing Classes:

NestedLoopJoinHasLeftJoinKey$Hib

public interface NestedLoopJoinHasLeftJoinKey
extends RefAssociation

NestedLoopJoinHasLeftJoinKey association proxy interface.

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(FemNestedLoopJoinStreamDef nestedLoopJoin, FemCorrelation leftJoinKey) Creates a link between the pair of instance objects in the associations link set.
boolean	exists(FemNestedLoopJoinStreamDef nestedLoopJoin, FemCorrelation leftJoinKey) Queries whether a link currently exists between a given pair of instance objects in the associations link set.
List<FemCorrelation>	getLeftJoinKey(FemNestedLoopJoinStreamDef nestedLoopJoin) Queries the instance objects that are related to a particular instance object by a link in the current associations link set.
FemNestedLoopJoinStreamDef	getNestedLoopJoin(FemCorrelation leftJoinKey) Queries the instance object that is related to a particular instance object by a link in the current associations link set.
boolean	remove(FemNestedLoopJoinStreamDef nestedLoopJoin, FemCorrelation leftJoinKey) Removes a link between a pair of instance objects in the current associations link set.

Method Detail

exists

boolean exists(FemNestedLoopJoinStreamDef nestedLoopJoin,
               FemCorrelation leftJoinKey)

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

Parameters:

nestedLoopJoin - Value of the first association end.

leftJoinKey - Value of the second association end.

Returns:

Returns true if the queried link exists.

getNestedLoopJoin

FemNestedLoopJoinStreamDef getNestedLoopJoin(FemCorrelation leftJoinKey)

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

Parameters:

leftJoinKey - Required value of the second association end.

Returns:

Related object or null if none exists.

getLeftJoinKey

List<FemCorrelation> getLeftJoinKey(FemNestedLoopJoinStreamDef nestedLoopJoin)

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

Parameters:

nestedLoopJoin - Required value of the first association end.

Returns:

List of related objects.

add

boolean add(FemNestedLoopJoinStreamDef nestedLoopJoin,
            FemCorrelation leftJoinKey)

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

Parameters:

nestedLoopJoin - Value of the first association end.

leftJoinKey - Value of the second association end.

remove

boolean remove(FemNestedLoopJoinStreamDef nestedLoopJoin,
               FemCorrelation leftJoinKey)

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

Parameters:

nestedLoopJoin - Value of the first association end.

leftJoinKey - Value of the second association end.
