Detailed Description

For providers only using the OpcUa_BaseNodes of the SDK there is no need to use any of the functions described in this module. All necessary work is done by the SDK, the provider only needs to call UaServer_BrowseInternal in its BrowseAsync implementation.

For providers implementing BrowseAsync themselves without using the SDK's UaServer_BrowseInternal helper function, it will get necessary to create ContinuationPoints. Following code example describes how to create ContinuationPoints inside a provider:

// Do the browsing, fill the results, check if a ContinuationPoint has to be created
UaServer_ContinuationPointInfo *pCPInfo = OpcUa_Null;
// Check if a ContinuationPointInfo already exists
if (a_pBrowseCtx->pContinuationPointInfo == OpcUa_Null)
{
    // Create a new UaServer_ContinuationPointInfo of type ContinuationPointType_Browse
    pCPInfo = UaServer_ContinuationPointInfo_Create(ContinuationPointType_Browse);
    // Create the actual ContinuationPoint sent to the client
    UaServer_ContinuationPointInfo_InitCPData(pCPInfo);
    // Remember the BrowseCall for the BrowseNext call the client will issue
    OpcUa_BrowseDescription_CopyTo(&pRequest->NodesToBrowse[a_iNodeIndex], (OpcUa_BrowseDescription*)pCPInfo->pDescription);
    pCPInfo->RequestedMaxReferencesPerNode = pRequest->RequestedMaxReferencesPerNode;
    // Add the ContinuationPointInfo to the Session's list of ContinuationPointInfos
    uStatusTemp = UaServer_ContinuationPointInfo_AddToList(pCPInfo, (UaServer_PublicSession*)pBrowseContext->pSession);
    if (OpcUa_IsBad(uStatusTemp))
    {
        UaServer_ContinuationPointInfo_Delete(pCPInfo);
        pCPInfo = OpcUa_Null;
    }
}
else
{
    pCPInfo = a_pBrowseCtx->pContinuationPointInfo;
}
if (pCPInfo != OpcUa_Null)
{
    // Set the offset for the next BrowseNext call
    a_pBrowseCtx->pContinuationPointInfo->NextTargetIndex = nextTargetIndex;
    // Set the actual ContinuationPoint in the browse response
    OpcUa_ByteString_CopyTo(a_pBrowseCtx->pContinuationPointInfo->pContinuationPoint,
                            &pResponse->Results[a_iNodeIndex].ContinuationPoint);
}
else
{
    // Error handling
}
