Class Extend

Namespace
NMF.Interop.Uml
Assembly
NMF.UMLInterop.dll

A relationship from an extending UseCase to an extended UseCase that specifies how and when the behavior defined in the extending UseCase can be inserted into the behavior defined in the extended UseCase. <p>From package UML::UseCases.</p>

Constructors

Extend()

Creates a new instance

public Extend()

Properties

Children

Gets the child model elements of this model element

public override IEnumerableExpression<IModelElement> Children { get; }

Property Value

IEnumerableExpression<IModelElement>

ClassInstance

Gets the Class model for this type

public static IClass ClassInstance { get; }

Property Value

IClass

Condition

References the condition that must hold when the first ExtensionPoint is reached for the extension to take place. If no constraint is associated with the Extend relationship, the extension is unconditional. <p>From package UML::UseCases.</p>

[Browsable(false)]
[XmlElementName("condition")]
[XmlAttribute(false)]
[Containment]
public IConstraint Condition { get; set; }

Property Value

IConstraint

ExtendedCase

The UseCase that is being extended. <p>From package UML::UseCases.</p>

[XmlElementName("extendedCase")]
[XmlAttribute(true)]
public IUseCase ExtendedCase { get; set; }

Property Value

IUseCase

Extension

The UseCase that represents the extension and owns the Extend relationship. <p>From package UML::UseCases.</p>

[Browsable(false)]
[XmlElementName("extension")]
[XmlAttribute(true)]
[XmlOpposite("extend")]
public IUseCase Extension { get; set; }

Property Value

IUseCase

ExtensionLocation

An ordered list of ExtensionPoints belonging to the extended UseCase, specifying where the respective behavioral fragments of the extending UseCase are to be inserted. The first fragment in the extending UseCase is associated with the first extension point in the list, the second fragment with the second point, and so on. Note that, in most practical cases, the extending UseCase has just a single behavior fragment, so that the list of ExtensionPoints is trivial. <p>From package UML::UseCases.</p>

[LowerBound(1)]
[XmlElementName("extensionLocation")]
[XmlAttribute(true)]
public IOrderedSetExpression<IExtensionPoint> ExtensionLocation { get; }

Property Value

IOrderedSetExpression<IExtensionPoint>

ReferencedElements

Gets the referenced model elements of this model element

public override IEnumerableExpression<IModelElement> ReferencedElements { get; }

Property Value

IEnumerableExpression<IModelElement>

Methods

Extension_points(object, object)

The ExtensionPoints referenced by the Extend relationship must belong to the UseCase that is being extended. extensionLocation->forAll (xp | extendedCase.extensionPoint->includes(xp))

public bool Extension_points(object diagnostics, object context)

Parameters

diagnostics object

The chain of diagnostics to which problems are to be appended.

context object

The cache of context-specific information.

Returns

bool

GetClass()

Gets the Class for this model element

public override IClass GetClass()

Returns

IClass

GetCollectionForFeature(string)

Gets the Model element collection for the given feature

protected override IList GetCollectionForFeature(string feature)

Parameters

feature string

The requested feature

Returns

IList

A non-generic list of elements

GetExpressionForReference(string)

Gets the property expression for the given reference

protected override INotifyExpression<IModelElement> GetExpressionForReference(string reference)

Parameters

reference string

The requested reference in upper case

Returns

INotifyExpression<IModelElement>

An incremental property expression

GetModelElementForReference(string, int)

Resolves the given URI to a child model element

protected override IModelElement GetModelElementForReference(string reference, int index)

Parameters

reference string

The requested reference name

index int

The index of this reference

Returns

IModelElement

The model element or null if it could not be found

GetRelativePathForNonIdentifiedChild(IModelElement)

Gets the relative URI fragment for the given child model element

protected override string GetRelativePathForNonIdentifiedChild(IModelElement element)

Parameters

element IModelElement

The element that should be looked for

Returns

string

A fragment of the relative URI

OnParentChanged(IModelElement, IModelElement)

Gets called when the parent model element of the current model element changes

protected override void OnParentChanged(IModelElement newParent, IModelElement oldParent)

Parameters

newParent IModelElement

The new parent model element

oldParent IModelElement

The old parent model element

OnParentChanging(IModelElement, IModelElement)

Gets called when the parent model element of the current model element is about to change

protected override void OnParentChanging(IModelElement newParent, IModelElement oldParent)

Parameters

newParent IModelElement

The new parent model element

oldParent IModelElement

The old parent model element

SetFeature(string, object)

Sets a value to the given feature

protected override void SetFeature(string feature, object value)

Parameters

feature string

The requested feature

value object

The value that should be set to that feature
