A link is an instance of an association. In the UML
Link is a sub-class of
Instance. Within a sequence diagram links are created
indirectly when an associated stimulus is created.
An link is represented on a sequence diagram in ArgoUML
as a line connecting the instances concerned. However on a
sequence diagram the representation is modified to reflect the
type of action associated with the stimulus carried on the link
(see Section 19.3, “Stimulus”).
