Examples with UaDataTypeNode org.eclipse.milo.opcua.sdk.client.nodes.UaDataTypeNode used on opensource projects

Example 1 with UaDataTypeNode

use of org.eclipse.milo.opcua.sdk.client.nodes.UaDataTypeNode in project milo by eclipse.

the class AddressSpace method createDataTypeNodeFromBaseAttributes.

private CompletableFuture<UaDataTypeNode> createDataTypeNodeFromBaseAttributes(NodeId nodeId, List<DataValue> baseAttributeValues) {
    Set<AttributeId> remainingAttributes = Sets.difference(AttributeId.DATA_TYPE_ATTRIBUTES, AttributeId.BASE_ATTRIBUTES);
    CompletableFuture<ReadResponse> attributesFuture = readAttributes(nodeId, remainingAttributes);
    return attributesFuture.thenCompose(response -> {
        List<DataValue> attributeValues = new ArrayList<>(baseAttributeValues);
        Collections.addAll(attributeValues, response.getResults());
        try {
            UaDataTypeNode node = newDataTypeNode(nodeId, attributeValues);
            nodeCache.put(node.getNodeId(), node);
            return completedFuture(node);
        } catch (UaException e) {
            return failedFuture(e);
        }
    });
}

Example 2 with UaDataTypeNode

use of org.eclipse.milo.opcua.sdk.client.nodes.UaDataTypeNode in project milo by eclipse.

the class AddressSpace method newDataTypeNode.

private UaDataTypeNode newDataTypeNode(NodeId nodeId, List<DataValue> attributeValues) throws UaException {
    DataValue nodeIdDataValue = attributeValues.get(0);
    StatusCode nodeIdStatusCode = nodeIdDataValue.getStatusCode();
    if (nodeIdStatusCode != null && nodeIdStatusCode.isBad()) {
        throw new UaException(nodeIdStatusCode);
    }
    try {
        NodeClass nodeClass = NodeClass.from((Integer) attributeValues.get(1).getValue().getValue());
        Preconditions.checkArgument(nodeClass == NodeClass.DataType, "expected NodeClass.DataType, got NodeClass." + nodeClass);
        QualifiedName browseName = (QualifiedName) attributeValues.get(2).getValue().getValue();
        LocalizedText displayName = (LocalizedText) attributeValues.get(3).getValue().getValue();
        LocalizedText description = getAttributeOrNull(attributeValues.get(4), LocalizedText.class);
        UInteger writeMask = getAttributeOrNull(attributeValues.get(5), UInteger.class);
        UInteger userWriteMask = getAttributeOrNull(attributeValues.get(6), UInteger.class);
        Boolean isAbstract = (Boolean) attributeValues.get(7).getValue().getValue();
        return new UaDataTypeNode(client, nodeId, nodeClass, browseName, displayName, description, writeMask, userWriteMask, isAbstract);
    } catch (Throwable t) {
        throw UaException.extract(t).orElse(new UaException(StatusCodes.Bad_UnexpectedError, t));
    }
