Class UML 2.4.1::InstanceSpecification

Description:

An instance specification has the capability of being a deployment target in a deployment relationship, in the case that it is an instance of a node. It is also has the capability of being a deployed artifact, if it is an instance of an artifact.An instance specification is a model element that represents an instance in a modeled system.

Direct Superclasses: DeployedArtifact, PackageableElement, DeploymentTarget

Direct Subclasses: EnumerationLiteral

Constraints:

Signature: structural_feature() : Boolean;
Description: One structural feature (including the same feature inherited from multiple classifiers) is the defining feature of at most one slot in an instance specification.
Expression: classifier->forAll(c | (c.allFeatures()->forAll(f | slot->select(s | s.definingFeature = f)->size() <= 1)))

Signature: deployment_target() : Boolean;
Description: An InstanceSpecification can be a DeploymentTarget if it is the instance specification of a Node and functions as a part in the internal structure of an encompassing Node.
Expression: true

Signature: deployment_artifact() : Boolean;
Description: An InstanceSpecification can be a DeployedArtifact if it is the instance specification of an Artifact.
Expression: true

Signature: defining_feature() : Boolean;
Description: The defining feature of each slot is a structural feature (directly or inherited) of a classifier of the instance specification.
Expression: slot->forAll(s | classifier->exists (c | c.allFeatures()->includes (s.definingFeature)))
