Example 1 with WriteContext

use of org.eclipse.milo.opcua.sdk.server.api.services.AttributeServices.WriteContext in project milo by eclipse.

the class DefaultAttributeServiceSet method onWrite.

@Override
public void onWrite(ServiceRequest service) {
    WriteRequest request = (WriteRequest) service.getRequest();
    OpcUaServer server = service.attr(ServiceAttributes.SERVER_KEY).get();
    Session session = service.attr(ServiceAttributes.SESSION_KEY).get();
    List<WriteValue> nodesToWrite = l(request.getNodesToWrite());
    if (nodesToWrite.isEmpty()) {
        service.setServiceFault(StatusCodes.Bad_NothingToDo);
        return;
    }
    if (nodesToWrite.size() > server.getConfig().getLimits().getMaxNodesPerWrite().intValue()) {
        service.setServiceFault(StatusCodes.Bad_TooManyOperations);
        return;
    }
    DiagnosticsContext<WriteValue> diagnosticsContext = new DiagnosticsContext<>();
    WriteContext context = new WriteContext(server, session, new DiagnosticsContext<>());
    server.getAddressSpaceManager().write(context, nodesToWrite);
    context.getFuture().thenAccept(values -> {
        ResponseHeader header = service.createResponseHeader();
        DiagnosticInfo[] diagnosticInfos = diagnosticsContext.getDiagnosticInfos(nodesToWrite);
        WriteResponse response = new WriteResponse(header, values.toArray(new StatusCode[0]), diagnosticInfos);
        service.setResponse(response);
    });
