Interface FeatureSlot

All Superinterfaces:

RefAssociation, RefBaseObject

All Known Implementing Classes:

FeatureSlot$Hib

public interface FeatureSlot
extends RefAssociation

FeatureSlot association proxy interface. The FeatureSlot association connects Slot instances with the StructuralFeature instance (usually either an Attribute or AssociationEnd instance) describing the structure of the value held by the Slot.

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, CwmSlot slot) Creates a link between the pair of instance objects in the associations link set.
boolean	exists(CwmStructuralFeature feature, CwmSlot slot) Queries whether a link currently exists between a given pair of instance objects in the associations link set.
CwmStructuralFeature	getFeature(CwmSlot slot) Queries the instance object that is related to a particular instance object by a link in the current associations link set.
Collection<CwmSlot>	getSlot(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, CwmSlot slot) Removes a link between a pair of instance objects in the current associations link set.

Method Detail

exists

boolean exists(CwmStructuralFeature feature,
               CwmSlot slot)

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.

slot - Value of the second association end.

Returns:

Returns true if the queried link exists.

getFeature

CwmStructuralFeature getFeature(CwmSlot slot)

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

Parameters:

slot - Required value of the second association end.

Returns:

Related object or null if none exists.

getSlot

Collection<CwmSlot> getSlot(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,
            CwmSlot slot)

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

Parameters:

feature - Value of the first association end.

slot - Value of the second association end.

remove

boolean remove(CwmStructuralFeature feature,
               CwmSlot slot)

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

Parameters:

feature - Value of the first association end.

slot - Value of the second association end.
