Hi everyone,
Firstly, i would like to explain my problem:
1. Problem: i created a plugin the permits to import papyrus models into the papyrus cdo model repository. For the purpose of overriding the attach/detach methods, i created a class that extends the CDOResourceImpl class. The problem is that, the attach/detach methods of my created class were not called when i add/delete elements of the models (because the created resources on the repository are instanceof the classic CDOReousrceImpl but not instancesof my created class).
2. What i did:
I created a PapyrusCDOResourceImpl class that extends the CDOResourceImpl class, and a resouce factory class :
class PapyrusCDOResourceFactoryImpl extends CDOResourceFactoryImpl
and then i tried to both register the resource factory class to the registry by using the ecore.protocole_parser extension point, and also register the registry programmatically like this:
Registry cdoReg = cdoTransaction_p.getResourceSet()
.getResourceFactoryRegistry();
Map<String, Object> protocolToFactoryMap = registry_p
.getProtocolToFactoryMap();
protocolToFactoryMap.remove(CDOProtocolConstants.PROTOCOL_NAME);
protocolToFactoryMap.put(CDOProtocolConstants.PROTOCOL_NAME,
new PapyrusCDOResourceFactoryImpl());
Thanks in advance for your help,
Kind Regards,
Hoa

Hi, Hoa,
Have you had a look at what the org.eclipse.papyrus.cdo.core.importer
package offers for importing resources from the workspace into a CDO
repository? Why do you need to change the behaviour of the attached()
and detached() methods? What specific problem is that trying to solve?
Perhaps there is already a solution available, or a better path to a
solution.
Cheers,
Christian
