Interface ElementConstraint

All Superinterfaces:

RefAssociation, RefBaseObject

All Known Implementing Classes:

ElementConstraint$Hib

public interface ElementConstraint
extends RefAssociation

ElementConstraint association proxy interface. The ElementConstraint association provides linkages between ModelElements and the Constraint instances that constrain their state. Note that a Constraint instance may not simultaneously participate in both the ElementConstraint and the StereotypeConstraint associations.

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(CwmModelElement constrainedElement, CwmConstraint constraint) Creates a link between the pair of instance objects in the associations link set.
boolean	exists(CwmModelElement constrainedElement, CwmConstraint constraint) Queries whether a link currently exists between a given pair of instance objects in the associations link set.
List<CwmModelElement>	getConstrainedElement(CwmConstraint constraint) Queries the instance objects that are related to a particular instance object by a link in the current associations link set.
Collection<CwmConstraint>	getConstraint(CwmModelElement constrainedElement) Queries the instance objects that are related to a particular instance object by a link in the current associations link set.
boolean	remove(CwmModelElement constrainedElement, CwmConstraint constraint) Removes a link between a pair of instance objects in the current associations link set.

Method Detail

exists

boolean exists(CwmModelElement constrainedElement,
               CwmConstraint constraint)

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

Parameters:

constrainedElement - Value of the first association end.

constraint - Value of the second association end.

Returns:

Returns true if the queried link exists.

getConstrainedElement

List<CwmModelElement> getConstrainedElement(CwmConstraint constraint)

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

Parameters:

constraint - Required value of the second association end.

Returns:

List of related objects.

getConstraint

Collection<CwmConstraint> getConstraint(CwmModelElement constrainedElement)

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

Parameters:

constrainedElement - Required value of the first association end.

Returns:

Collection of related objects.

add

boolean add(CwmModelElement constrainedElement,
            CwmConstraint constraint)

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

Parameters:

constrainedElement - Value of the first association end.

constraint - Value of the second association end.

remove

boolean remove(CwmModelElement constrainedElement,
               CwmConstraint constraint)

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

Parameters:

constrainedElement - Value of the first association end.

constraint - Value of the second association end.
