testcase. An uml2 resource containing all JDK classes

Testcase:
It is an UML2 Resource (jdk.uml2) that contains all the classes from JDK
(rt.jar). 
It is an example of a big resource that makes unusable the destroy operation,
because it is too slow (it spend minutes to destroy a newly created package)

Prototype implementation for dynamic maintaining inverses of uni-directional references

Feedback one the prototype will be welcome

Comment 4 Vishy Ramaswamy 2005-11-08 13:14:37 EST

Hi Ed,
The implementation in the prototype is not accounting for derived references as
shown below:

protected boolean crossReference(EObject eObject, EReference eReference, 
EObject crossReferencedEObject) { 
return eReference.getEOpposite() == null && !eReference.isDerived();
} 

Ideally the following are required in order to find the entire set of 
references to an EObject:
Containment References:Can be computed at runtime using the EObject's 
eContainmentFeature
Non-Containment uni-directional References: Need to be stored in the map
Derived References: Need to be stored in the map since it cant be computed 
from the referenced EObject
References that are bi-directional(eopposite): Can be computed from the 
reference features of the EObject

So I think derived references should also be included in the map. Please 
correct me if any of the above assumptions are incorrect. Your thoughts?
Vishy

The prototype with the isDerived guard removed has been committed to CVS.
