Interface Constraint

All Superinterfaces:

Element, org.eclipse.emf.ecore.EModelElement, org.eclipse.emf.ecore.EObject, NamedElement, org.eclipse.emf.common.notify.Notifier, PackageableElement, ParameterableElement

All Known Subinterfaces:

DurationConstraint, InteractionConstraint, IntervalConstraint, TimeConstraint

public interface Constraint
extends PackageableElement

A representation of the model object 'Constraint'. A Constraint is a condition or restriction expressed in natural language text or in a machine readable language for the purpose of declaring some of the semantics of an Element or set of Elements.

From package UML::CommonStructure.

The following features are supported:

• Constrained Element
• Context
• Specification

boolean	validateBooleanValue(org.eclipse.emf.common.util.DiagnosticChain diagnostics, java.util.Map<java.lang.Object,java.lang.Object> context) The ValueSpecification for a Constraint must evaluate to a Boolean value.
boolean	validateNoSideEffects(org.eclipse.emf.common.util.DiagnosticChain diagnostics, java.util.Map<java.lang.Object,java.lang.Object> context) Evaluating the ValueSpecification for a Constraint must not have side effects.

Method Detail

getConstrainedElements

org.eclipse.emf.common.util.EList<Element> getConstrainedElements()

Returns the value of the 'Constrained Element' reference list. The list contents are of type Element. The ordered set of Elements referenced by this Constraint.

From package UML::CommonStructure.

Returns:

the value of the 'Constrained Element' reference list.

See Also:

UMLPackage.getConstraint_ConstrainedElement()

getSpecification

ValueSpecification getSpecification()

Returns the value of the 'Specification' containment reference.

This feature subsets the following features:

• 'Owned Element'

A condition that must be true when evaluated in order for the Constraint to be satisfied.

From package UML::CommonStructure.

Returns:

the value of the 'Specification' containment reference.

See Also:

setSpecification(ValueSpecification), UMLPackage.getConstraint_Specification()

setSpecification

void setSpecification(ValueSpecification value)

Sets the value of the 'Specification' containment reference.

Parameters:

value - the new value of the 'Specification' containment reference.

See Also:

getSpecification()

createSpecification

ValueSpecification createSpecification(java.lang.String name,
                                       Type type,
                                       org.eclipse.emf.ecore.EClass eClass)

Creates a new ValueSpecification, with the specified 'Name', and 'Type', and sets the 'Specification' containment reference.

Parameters:

name - The 'Name' for the new ValueSpecification, or null.

type - The 'Type' for the new ValueSpecification, or null.

eClass - The Ecore class of the ValueSpecification to create.

Returns:

The new ValueSpecification.

See Also:

getSpecification()

getContext

Namespace getContext()

Returns the value of the 'Context' container reference. It is bidirectional and its opposite is 'Owned Rule'.

This feature subsets the following features:

• 'Namespace'

Specifies the Namespace that owns the Constraint.

From package UML::CommonStructure.

Returns:

the value of the 'Context' container reference.

See Also:

setContext(Namespace), UMLPackage.getConstraint_Context(), Namespace.getOwnedRules()

setContext

void setContext(Namespace value)

Sets the value of the 'Context' container reference.

Parameters:

value - the new value of the 'Context' container reference.

See Also:

getContext()
