AssociationClass & Operations?

[Paolo F Cantoni]

Following on from Jim Shaw's question about Associations, it got me wondering...

Can an AssociationClass have Operations (methods)?

I've never really thought about it much, but from memory, all the ones I've created had only Attributes (or at most Setters and Getters for equivalent Properties).

Thoughts anyone?

Triggers in an according database table?

I think from 7.3.4 and 7.3.5 of the UJML spec, it is entirely possible for an AssociationClass to have a behavior.


For example, such an association, having a temporal constraint, could notify other objects when the constraint is satisfied or dissatisfied.  When a part-time employee comes into his scheduled work period, the association could notify a combo-box listing currently active employees.
