An Operation is a BehavioralFeature of a Classifier that specifies the name, type, parameters, and constraints for invoking an associated Behavior. An Operation may invoke both the execution of method behaviors as well as other behavioral responses.

| Name | Type | Description |
|---|---|---|
| appliedStereotypes | Stereotype [0..*] | Indicates which stereotypes from the selected profile (or profiles) are applied to the element. The selected profiles are the profiles that are applied to the containing package. Inherited from Element. |
| id | string | Gets the unique ID of the element. Inherited from Element. |
| isAbstract | boolean | If true, then the BehavioralFeature does not have an implementation, and one must be supplied by a more specific Classifier. If false, the BehavioralFeature must have an implementation in the Classifier or one must be inherited. Inherited from BehavioralFeature. |
| isConstructor | boolean | Specifies if the operation is a class constructor. |
| isLeaf | boolean | Indicates whether it is possible to further redefine a RedefinableElement. If the value is true, then it is not possible to further redefine the RedefinableElement. Inherited from RedefinableElement. |
| isQuery | boolean | Specifies whether an execution of the BehavioralFeature leaves the state of the system unchanged (isQuery=true) or whether side effects may occur (isQuery=false). |
| isStatic | boolean | Specifies whether this Feature characterizes individual instances classified by the Classifier (false) or the Classifier itself (true). Inherited from Feature. |
| lower | integer [0..1] | Gets the lower bound of the return parameter, if present. This information is derived from the return result for this Operation. |
| name | string | The name of the NamedElement. Inherited from NamedElement. |
| order | integer [1..1] | Gets or set the sort order of the element if it is part of a collection. The value is 0 for elements to which no particular ordering applies. Elements with a lower order come before elements with a higher order. Inherited from OrderedElement. |
| ownedComments | Comment [0..*] | The Comments owned by this Element. Inherited from Element. |
| ownedParameters | Parameter [0..*] | The parameters owned by this Operation. Inherited from BehavioralFeature. |
| owner | Element [0..1] | Gets the element that owns this element. Inherited from Element. |
| taggedValues | TaggedValueSpecification [0..*] | Contains 0 or more tagged values for the element. Inherited from Element. |
| upper | UnlimitedNatural [0..1] | The upper bound of the return parameter, if present. This information is derived from the return result for this Operation. |
| visibility | VisibilityKind [0..1] | Determines whether and how the NamedElement is visible outside its owning Namespace. Inherited from NamedElement. |
| Name | Returns | Description |
|---|---|---|
getFirstCommentBody()Operation.getFirstCommentBodyXGets the text contents of the first comment in the element's owned comments, or an empty string if the element has no comments. Return valueType: string [1..1]The body string of the first comment. If the element has no comments, an empty string is returned. | string [1..1] | Gets the text contents of the first comment in the element's owned comments, or an empty string if the element has no comments. Inherited from Element. |
| getInputParameters() | Parameter [0..*] | Returns the ownedParameters with direction in and inout. |
getLowerBound()Operation.getLowerBoundXThe query lowerBound() returns the lower bound of the return parameter as an integer, which is the integerValue of lowerValue, if this is given, and 1 otherwise. This information is derived from the return result for this Operation. Return valueType: integer | integer | The query lowerBound() returns the lower bound of the return parameter as an integer, which is the integerValue of lowerValue, if this is given, and 1 otherwise. This information is derived from the return result for this Operation. |
| getOutputParameters() | Parameter [0..*] | Returns the ownedParameters with direction out, inout, or return. |
| getReturnParameter() | Parameter [0..1] | Gets the operation's return parameter, if it has one. |
| getReturnType() | Type [0..1] | Gets the type of the operation's return parameter, if it has any. |
getUpperBound()Operation.getUpperBoundXThe query upperBound() returns the upper bound of the return parameter for a bounded multiplicity as an unlimited natural, which is the unlimitedNaturalValue of upperValue, if given, and 1, otherwise. This information is derived from the return result for this Operation. Return valueType: UnlimitedNatural | UnlimitedNatural | The query upperBound() returns the upper bound of the return parameter for a bounded multiplicity as an unlimited natural, which is the unlimitedNaturalValue of upperValue, if given, and 1, otherwise. This information is derived from the return result for this Operation. |
isMultivalued()Operation.isMultivaluedXThe query isMultivalued() checks whether the return parameter has an upper bound greater than one. Return valueType: boolean | boolean | The query isMultivalued() checks whether the return parameter has an upper bound greater than one. |
isOptional()Operation.isOptionalXThe query isOptional checks whether he return parameter has a lower bound of 0 (0..n). Return valueType: boolean | boolean | The query isOptional checks whether he return parameter has a lower bound of 0 (0..n). |
isOptionalAndSinglevalued()Operation.isOptionalAndSinglevaluedXThe query isOptional checks whether he return parameter has a lower bound of 0 and an upper bound of 1 (0..1). Return valueType: boolean | boolean | The query isOptional checks whether he return parameter has a lower bound of 0 and an upper bound of 1 (0..1). |
