IOperation Interface

Specifies the name, type, parameters, and constraints for invoking an associated behavior.

Namespace:  Microsoft.VisualStudio.Uml.Classes
Assembly:  Microsoft.VisualStudio.Uml.Interfaces (in Microsoft.VisualStudio.Uml.Interfaces.dll)

public interface IOperation : IBehavioralFeature, 
	IFeature, IRedefinableElement, INamespace, ITemplateableElement, IParameterableElement, 
	INamedElement, IElement

The IOperation type exposes the following members.

Public propertyApplicableStereotypesThe set of stereotypes that could be applied to this element. (Inherited from IElement.)
Public propertyAppliedStereotypesEach IStereotypeInstance denotes that a stereotype has been applied to this element. (Inherited from IElement.)
Public propertyBodyConditionsGets a constraint on the values returned from the Operation. Defined only if IsQuery = True.
Public propertyClassGets the Class that owns this operation. May be null.
Public propertyClientDependenciesGets the Dependency relationships for which this element is the Client. (Inherited from INamedElement.)
Public propertyConcurrencyDefines 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.)
Public propertyDescriptionThe description of this element. (Inherited from IElement.)
Public propertyFeaturingClassifiersGets the Classifiers on which this Feature appears. (Inherited from IFeature.)
Public propertyInterfaceGets the Interface that owns this Operation. May be null.
Public propertyIsAbstractTrue if this is a partial description intended to be extended or overridden in specializing classes. (Inherited from IBehavioralFeature.)
Public propertyIsLeafTrue if this element should not be specialized. That is, it should not be the target of a Generalization relationship. (Inherited from IRedefinableElement.)
Public propertyIsOrderedFor a return type with multiplicity > 1. True if the returned collection forms a sequence with a definite ordering.
Public propertyIsQueryTrue if execution of the Operation leaves the state of the system unchanged.
Public propertyIsStaticTrue 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.)
Public propertyIsUniqueFor a return type with multiplicity > 1. True if each value in the returned collection is different from the other values.
Public propertyLower Gets the lower multiplicity of the return value, if there is one.
Public propertyMembersGets the elements that are part of this Namespace. (Inherited from INamespace.)
Public propertyMethodsGets 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.)
Public propertyNameThe 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.)
Public propertyNamespaceGets the Namespace in which this element is defined. May be null. (Inherited from INamedElement.)
Public propertyOwnedCommentsGets Comments contained in this element (not comments linked to it). (Inherited from IElement.)
Public propertyOwnedElementsGets Elements owned by this element. Every element has one owner, except the root IModel. (Inherited from IElement.)
Public propertyOwnedMembersGets the elements that are defined within this Namespace. (Inherited from INamespace.)
Public propertyOwnedParametersGets the ordered set of formal parameters owned by this BehavioralFeature. The parameter direction can be in, inout, out, or return. (Inherited from IBehavioralFeature.)
Public propertyOwnerGets the Element that owns this element. Every element except the root IModel has one owner. (Inherited from IElement.)
Public propertyOwningTemplateParameterIf not null, this element is defined as a parameter in a template. (Inherited from IParameterableElement.)
Public propertyPackageImportsGets the packages that are imported by this namespace. (Inherited from INamespace.)
Public propertyPostconditions Gets the Constraints that should be satisfied when the Operation completes.
Public propertyPreconditionsGets the constraints that should be satisfied before the Operation is invoked.
Public propertyQualifiedNameGets 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.)
Public propertySignatureGets a string representing the visibility, name, parameters, and return type of the Operation. For example: +Cook(p1:Heat):Food
Public propertyTemplateBindingsGets the Bindings in which this element is used. (Inherited from ITemplateableElement.)
Public propertyTemplateParameterIf not null, this element is defined as a parameter in a template. (Inherited from IParameterableElement.)
Public propertyTypeThe type of the return value, if there is one.
Public propertyUpperGets the upper multiplicity of the return value, if there is one.
Public propertyVisibilityDefines 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.)
Public propertyVisibleAppliedStereotypes (Inherited from IElement.)

Public Extension MethodAddReferenceLinks 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.)
Public Extension MethodApplyStereotypeApplies the stereotype to element. Creates an IStereotypeInstance that represents the extension of the model element by the stereotype. (Defined by ProfileStereotypeExtensions.)
Public Extension MethodCreateBodyConditionConstraintCreate a new bodyCondition IConstraint owned by Operation. (Defined by OperationExtensions.)
Public Extension MethodCreatePackageImportImport a package into a namespace. Creates an IPackageImport link to the package. (Defined by NamespaceExtensions.)
Public Extension MethodCreateParameterCreate a new IParameter object in the Behavioral Feature (Defined by BehavioralFeatureExtensions.)
Public Extension MethodCreatePostconditionConstraintCreate a new postcondition IConstraint owned by Operation. (Defined by OperationExtensions.)
Public Extension MethodCreatePreconditionConstraintCreate a new precondition IConstraint owned by Operation. (Defined by OperationExtensions.)
Public Extension MethodDeleteDeletes this element and any relationships, owned elements, and shapes. (Defined by UmlExtensions.)
Public Extension MethodDeleteAllReferenceRemove all the references of a given tag. (Defined by UmlExtensions.)
Public Extension MethodGetDependencyClientsReturn a collection of elements that are dependent on this. (Defined by NamedElementExtensions.)
Public Extension MethodGetDependencySuppliersReturn a collection of elements on which this is dependent. (Defined by NamedElementExtensions.)
Public Extension MethodGetIdGets a GUID that identifies this element. (Defined by UmlExtensions.)
Public Extension MethodGetImportedPackagesThe imported packages of the namespace (Defined by PackageExtensions.)
Public Extension MethodGetModelStoreGets the IModelStore that contains this element. (Defined by UmlExtensions.)
Public Extension MethodGetReferencesGet the IReferences of a given tag that are associated with this element. (Defined by UmlExtensions.)
Public Extension MethodGetRelatedElements<T>Gets elements related to this element by relationships of the specified type. (Defined by UmlExtensions.)
Public Extension MethodGetRelatedLinks<T>Gets relationships of a specified type from or to this element. (Defined by UmlExtensions.)
Public Extension MethodShapesAll the shapes that display the model element on any open diagram, or on a specified open diagram. (Defined by PresentationHelpers.)


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.
