Finding ParentId from a reference.

[xydan83]

Hi again)) There is some code in import.c

Code num 1.

static NL_Reference *getHierachicalInverseReference(const NL_Node *node)
{

    NL_Reference *hierachicalRef = node->hierachicalRefs;
    while (hierachicalRef)
    {
        if (!hierachicalRef->isForward)
        {
            return hierachicalRef;
        }
        hierachicalRef = hierachicalRef->next;
    }
    return NULL;
}

And this code (num 2):

static UA_NodeId getParentId(const NL_Node *node, UA_NodeId *parentRefId)
{
    UA_NodeId parentId = UA_NODEID_NULL;

    if(NodesetLoader_isInstanceNode(node))
    {
        parentId = ((const NL_InstanceNode*)node)->parentNodeId;
    }
    NL_Reference *ref = getHierachicalInverseReference((const NL_Node *)node);
    *parentRefId = getReferenceTypeId(ref);
    if (UA_NodeId_equal(&parentId, &UA_NODEID_NULL))
    {
        parentId = getReferenceTarget(ref);
    }
    return parentId;
}

I have a question. If we can't find the ParentNodeId from ((const NL_InstanceNode*)node)->parentNodeId; and we need to find it by reference, we try to find it by the first inverse reference (code number 1). But the references are sorted before it or not?

the first inverse hierachical reference is taken, they are not sorted
