Suppose a fictitious UML profile called 'Shaddock' defines a stereotype|
that extends uml:Class.
The following OCL snippet seems to determine whether the application of
the 'Shaddock' profile was strict or not.
| pa.appliedProfile.getLabel() = 'Shaddock' and pa.isStrict)
If I have N stereotypes that need to know ProfileApplication.isStrict
and they are instantiated on average M times, then I'll have N*M
expensive queries whenever I do full-scale validation.
Since I am using RSA 220.127.116.11, I'm bound to the limitations of the
UML/OCL implementation in Eclipse 3.2 which doesn't have support for
derived values. With derived values, I know -- at least in principle --
how to solve this problem better. Without derived values, I don't know
how to solve this problem without paying the O(N*M) complexity tax.
