Interface InstanceClassifier

All Superinterfaces:

RefAssociation, RefBaseObject

All Known Implementing Classes:

InstanceClassifier$Hib

public interface InstanceClassifier
extends RefAssociation

InstanceClassifier association proxy interface. The InstanceClassifier association links Instances with Classifiers that describe them.

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(CwmInstance instance, CwmClassifier classifier) Creates a link between the pair of instance objects in the associations link set.
boolean	exists(CwmInstance instance, CwmClassifier classifier) Queries whether a link currently exists between a given pair of instance objects in the associations link set.
CwmClassifier	getClassifier(CwmInstance instance) Queries the instance object that is related to a particular instance object by a link in the current associations link set.
Collection<CwmInstance>	getInstance(CwmClassifier classifier) Queries the instance objects that are related to a particular instance object by a link in the current associations link set.
boolean	remove(CwmInstance instance, CwmClassifier classifier) Removes a link between a pair of instance objects in the current associations link set.

Method Detail

exists

boolean exists(CwmInstance instance,
               CwmClassifier classifier)

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

Parameters:

instance - Value of the first association end.

classifier - Value of the second association end.

Returns:

Returns true if the queried link exists.

getInstance

Collection<CwmInstance> getInstance(CwmClassifier classifier)

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

Parameters:

classifier - Required value of the second association end.

Returns:

Collection of related objects.

getClassifier

CwmClassifier getClassifier(CwmInstance instance)

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

Parameters:

instance - Required value of the first association end.

Returns:

Related object or null if none exists.

add

boolean add(CwmInstance instance,
            CwmClassifier classifier)

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

Parameters:

instance - Value of the first association end.

classifier - Value of the second association end.

remove

boolean remove(CwmInstance instance,
               CwmClassifier classifier)

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

Parameters:

instance - Value of the first association end.

classifier - Value of the second association end.
