Class UML 2.5::Extend
Description:
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.Direct Superclasses: NamedElement, DirectedRelationshipDirect Subclasses: Class Precedence List: Extend, NamedElement, DirectedRelationship, Relationship, ElementProperties:

of nested Namespaces. It is constructed from the names of the containing
Namespaces starting at the root of the hierarchy and ending with the name
of the NamedElement itself.{readonly, derived}
