The IOperation type exposes the following members.

Properties

	Name	Description
	ApplicableStereotypes	The set of stereotypes that could be applied to this element. (Inherited from IElement.)
	AppliedStereotypes	Each IStereotypeInstance denotes that a stereotype has been applied to this element. (Inherited from IElement.)
	BodyConditions	Gets a constraint on the values returned from the Operation. Defined only if IsQuery = True.
	Class	Gets the Class that owns this operation. May be null.
	ClientDependencies	Gets the Dependency relationships for which this element is the Client. (Inherited from INamedElement.)
	Concurrency	Defines how calls from separate threads are processed. Sequential = the feature is not designed to handle concurrent calls; Guarded = calls will be blocked so that only one is processed at a time; concurrent = multiple calls can proceed concurrently. (Inherited from IBehavioralFeature.)
	Description	The description of this element. (Inherited from IElement.)
	FeaturingClassifiers	Gets the Classifiers on which this Feature appears. (Inherited from IFeature.)
	Interface	Gets the Interface that owns this Operation. May be null.
	IsAbstract	True if this is a partial description intended to be extended or overridden in specializing classes. (Inherited from IBehavioralFeature.)
	IsLeaf	True if this element should not be specialized. That is, it should not be the target of a Generalization relationship. (Inherited from IRedefinableElement.)
	IsOrdered	For a return type with multiplicity > 1. True if the returned collection forms a sequence with a definite ordering.
	IsQuery	True if execution of the Operation leaves the state of the system unchanged.
	IsStatic	True if this feature is shared by all the instances of its classifier. False if each instance effectively has a separate copy of the feature. (Inherited from IFeature.)
	IsUnique	For a return type with multiplicity > 1. True if each value in the returned collection is different from the other values.
	Lower	Gets the lower multiplicity of the return value, if there is one.
	Members	Gets the elements that are part of this Namespace. (Inherited from INamespace.)
	Methods	Gets Methods that implement the Behavioral Feature. There may be at most one behavior for each pairing of a classifier (as owner of the behavior) and a behavioral feature (as specification of the behavior). (Inherited from IBehavioralFeature.)
	Name	The name of this element within the Namespace that contains it. In this Namespace, there should be no other element that has this Name. (Inherited from INamedElement.)
	Namespace	Gets the Namespace in which this element is defined. May be null. (Inherited from INamedElement.)
	OwnedComments	Gets Comments contained in this element (not comments linked to it). (Inherited from IElement.)
	OwnedElements	Gets Elements owned by this element. Every element has one owner, except the root IModel. (Inherited from IElement.)
	OwnedMembers	Gets the elements that are defined within this Namespace. (Inherited from INamespace.)
	OwnedParameters	Gets the ordered set of formal parameters owned by this BehavioralFeature. The parameter direction can be in, inout, out, or return. (Inherited from IBehavioralFeature.)
	Owner	Gets the Element that owns this element. Every element except the root IModel has one owner. (Inherited from IElement.)
	OwningTemplateParameter	If not null, this element is defined as a parameter in a template. (Inherited from IParameterableElement.)
	PackageImports	Gets the packages that are imported by this namespace. (Inherited from INamespace.)
	Postconditions	Gets the Constraints that should be satisfied when the Operation completes.
	Preconditions	Gets the constraints that should be satisfied before the Operation is invoked.
	QualifiedName	Gets the name of this element, prefixed with the Qualified Name of the Namespace that contains it. Empty if the Name is empty or if the Qualified Name of the Namespace is empty. (Inherited from INamedElement.)
	Signature	Gets a string representing the visibility, name, parameters, and return type of the Operation. For example: +Cook(p1:Heat):Food
	TemplateBindings	Gets the Bindings in which this element is used. (Inherited from ITemplateableElement.)
	TemplateParameter	If not null, this element is defined as a parameter in a template. (Inherited from IParameterableElement.)
	Type	The type of the return value, if there is one.
	Upper	Gets the upper multiplicity of the return value, if there is one.
	Visibility	Defines where the element can be referenced. Public = visible anywhere; private = visible only in the owning Namespace; protected = visible to elements that have a generalization relationship to the owning Namespace; package = visible only in the Package owning the Namespace, if there is one. Default = public. (Inherited from INamedElement.)
	VisibleAppliedStereotypes	(Inherited from IElement.)

Extension Methods

	Name	Description
	AddReference	Links a string to an element, usually where the string is a reference such as a URI, modelbus reference, or work item ID. Use the name to indicate the type of reference. Returns an IReference object that represents the link. (Defined by UmlExtensions.)
	ApplyStereotype	Applies the stereotype to element. Creates an IStereotypeInstance that represents the extension of the model element by the stereotype. (Defined by ProfileStereotypeExtensions.)
	CreateBodyConditionConstraint	Create a new bodyCondition IConstraint owned by Operation. (Defined by OperationExtensions.)
	CreatePackageImport	Import a package into a namespace. Creates an IPackageImport link to the package. (Defined by NamespaceExtensions.)
	CreateParameter	Create a new IParameter object in the Behavioral Feature (Defined by BehavioralFeatureExtensions.)
	CreatePostconditionConstraint	Create a new postcondition IConstraint owned by Operation. (Defined by OperationExtensions.)
	CreatePreconditionConstraint	Create a new precondition IConstraint owned by Operation. (Defined by OperationExtensions.)
	Delete	Deletes this element and any relationships, owned elements, and shapes. (Defined by UmlExtensions.)
	DeleteAllReference	Remove all the references of a given tag. (Defined by UmlExtensions.)
	GetDependencyClients	Return a collection of elements that are dependent on this. (Defined by NamedElementExtensions.)
	GetDependencySuppliers	Return a collection of elements on which this is dependent. (Defined by NamedElementExtensions.)
	GetId	Gets a GUID that identifies this element. (Defined by UmlExtensions.)
	GetImportedPackages	The imported packages of the namespace (Defined by PackageExtensions.)
	GetModelStore	Gets the IModelStore that contains this element. (Defined by UmlExtensions.)
	GetReferences	Get the IReferences of a given tag that are associated with this element. (Defined by UmlExtensions.)
	GetRelatedElements<T>	Gets elements related to this element by relationships of the specified type. (Defined by UmlExtensions.)
	GetRelatedLinks<T>	Gets relationships of a specified type from or to this element. (Defined by UmlExtensions.)
	Shapes	All the shapes that display the model element on any open diagram, or on a specified open diagram. (Defined by PresentationHelpers.)

Remarks

Note

The methods defined on this type are extension methods. To use the methods, you must add a project reference to the .NET assembly Microsoft.VisualStudio.ArchitectureTools.Extensibility.dll, and you must include the directive using Microsoft.VisualStudio.ArchitectureTools.Extensibility.Uml; in your code.
