Hi, Andrew,
Yes and no. :-)
In the case that you are using the Ecore metamodel binding for OCL, then
yes, the type of 'o' is determined by EMF's reflection API:
EObject.eClass().
However, in the case of the UML metamodel binding -- which is used with EMF
models that are specified with UML, not Ecore, and are generated by MDT
UML2 (as UML2 is, itself) -- the metaclass of your element o is the
Operation class from the UML.metamodel.uml model, not the Operation EClass
from the UML.ecore model. Have a look at
OCLUMLUtil.getClassifier(EClassifier) for how this works.
Cheers,
Christian
