Yes, in general you can define operations with bodies (that use Xbase
syntax) and those bodies can refer to things in the model. In this
case, you've not defined an inverse reference for
AtomicComponent.computationUnit so you'd have to navigate from the
CompilationUnit to its container via EObject.eContainer() and cast it.
Probably nicer is to define a "container" reference in CompilationUnit
to access the containing AtomicComponent and from that you can of course
access all the features of a Component...
