org.apache.abdera.protocol.server.CollectionAdapter
The CollectionAdapter interface is the component that provides the business logic of an Atompub server. The Provider will use it's WorkspaceManager to determine which CollectionAdapter to dispatch a request to. Once an adapter is selected, the Provider will determine what kind of request is being made and will forward the request on to the appropriate CollectionAdapter method.

        if (processor == null) {
            return ProviderHelper.notfound(request);
        }


        WorkspaceManager wm = getWorkspaceManager(request);
        CollectionAdapter adapter = wm.getCollectionAdapter(request);
        Transactional transaction = adapter instanceof Transactional ? (Transactional) adapter : null;
        ResponseContext response = null;
        try {
            transactionStart(transaction, request);
            response = processor.process(request, wm, adapter);
