Link shape

A link UML Link shape icon is an instance of an association and represents references between objects. It can be binary, in which case it is a path between two objects, or reflexive, in which case it involves a loop with each end attached to the same object. If the association name is shown, it is underlined to indicate an instance.

End names, aggregation, composition, navigability, and other adornments can be shown on the link ends or roles, but because links are instances, their ends do not show multiplicity. A link can also have a stereotype to indicate a particular kind of implementation.
