Example 1 with RelativePath

use of org.eclipse.milo.opcua.stack.core.types.structured.RelativePath in project milo by eclipse.

the class BrowsePathsHelper method translate.

private CompletableFuture<BrowsePathResult> translate(BrowsePath browsePath) {
    CompletableFuture<BrowsePathResult> future = new CompletableFuture<>();
    NodeId startingNode = browsePath.getStartingNode();
    RelativePath relativePath = browsePath.getRelativePath();
    if (startingNode.isNull()) {
        future.complete(new BrowsePathResult(new StatusCode(StatusCodes.Bad_NodeIdInvalid), new BrowsePathTarget[0]));
        return future;
    }
    List<RelativePathElement> relativePathElements = l(relativePath.getElements());
    if (relativePathElements.isEmpty()) {
        future.complete(new BrowsePathResult(new StatusCode(StatusCodes.Bad_NothingToDo), new BrowsePathTarget[0]));
        return future;
    }
    follow(startingNode, relativePathElements).whenComplete((targets, ex) -> {
        if (targets != null) {
            BrowsePathResult result;
            if (!targets.isEmpty()) {
                result = new BrowsePathResult(StatusCode.GOOD, a(targets, BrowsePathTarget.class));
            } else {
                result = new BrowsePathResult(new StatusCode(StatusCodes.Bad_NoMatch), new BrowsePathTarget[0]);
            }
            future.complete(result);
        } else {
            StatusCode statusCode = UaException.extractStatusCode(ex).orElse(new StatusCode(StatusCodes.Bad_NoMatch));
            BrowsePathResult result = new BrowsePathResult(statusCode, new BrowsePathTarget[0]);
            future.complete(result);
        }
    });
    return future;
}

Example 2 with RelativePath

use of org.eclipse.milo.opcua.stack.core.types.structured.RelativePath in project milo by eclipse.

the class TranslateBrowsePathExample method run.

@Override

    // synchronous connect
    client.connect().get();
    TranslateBrowsePathsToNodeIdsResponse response = client.translateBrowsePaths(newArrayList(new BrowsePath(Identifiers.ObjectsFolder, new RelativePath(new RelativePathElement[] { new RelativePathElement(Identifiers.HierarchicalReferences, false, true, new QualifiedName(2, "HelloWorld")), new RelativePathElement(Identifiers.HierarchicalReferences, false, true, new QualifiedName(2, "ScalarTypes")), new RelativePathElement(Identifiers.HierarchicalReferences, false, true, new QualifiedName(2, "UInt64")) })))).get();
    BrowsePathResult result = l(response.getResults()).get(0);
    StatusCode statusCode = result.getStatusCode();
    logger.info("Status={}", statusCode);
    l(result.getTargets()).forEach(target -> logger.info("TargetId={}", target.getTargetId()));
    future.complete(client);
