Examples of org.jboss.dna.graph.request.VerifyNodeExistsRequest

org.jboss.dna.graph.request.VerifyNodeExistsRequest
Instruction to verify the existance of a node at the specified location. This request also returns the actual location.

            FederatedRequest federatedRequest = new FederatedRequest(request);
            while (projectedNode != null) {
                if (projectedNode.isPlaceholder()) {
                    PlaceholderNode placeholder = projectedNode.asPlaceholder();
                    // Create a request and set the results ...
                    VerifyNodeExistsRequest placeholderRequest = new VerifyNodeExistsRequest(root, workspace.getName());
                    placeholderRequest.setActualLocationOfNode(placeholder.location());
                    federatedRequest.add(placeholderRequest, true, true, null);
                } else if (projectedNode.isProxy()) {
                    ProxyNode proxy = projectedNode.asProxy();
                    // Create and submit a request for the projection ...
                    VerifyNodeExistsRequest pushDownRequest = new VerifyNodeExistsRequest(proxy.location(), proxy.workspaceName());
                    federatedRequest.add(pushDownRequest, proxy.isSameLocationAsOriginal(), false, proxy.projection());
                }
                projectedNode = projectedNode.next();
            }
            // Submit for processing ...
