[news.eclipse.modeling.mdt.ocl] Re: def expression?

["Christian W. Damus" <cdamus@xxxxxxx>]

Hi, Joel,

If the SDK documentation doesn't provide examples, then your best bet is to look into the JUnit tests.  Search for invocations of the OCLHelper methods in the org.eclipse.ocl.ecore.tests plug-in, for example.  They should all be covered, IIRC.

HTH,

Christian
