In object model diagrams, you can select associations for
classes that have more than one association defined between the same
two classes. To do this, right-click an association line and then
select Select Association.
Association names are displayed as follows:
- If the association has a name, the name is listed.
- If the association does not have a name and it
is symmetric, the identifier uses the format <role_1>-<role_2>.
- If the association does not have a name and it
is unidirectional, the identifier uses the format -><role>.
- If you select a different association from the
list, the association line is directed to reference the selected association.
