Class ExportSearchNodesHelper

java.lang.Object
fr.becpg.repo.report.helpers.ExportSearchNodesHelper
public final class ExportSearchNodesHelper extends Object

Stores the nodes of an asynchronous search export on their download node, as a JSON array in its cm:content property.

Attaching one association per exported node saturates the transactional caches and holds the database locks of the download node for the whole request: a single content write does not, and lets the client progress bar start without waiting. The content is later replaced by the produced archive once the export completes.

    readNodes(org.alfresco.service.cmr.repository.ContentService contentService, org.alfresco.service.cmr.repository.NodeService nodeService, org.alfresco.service.cmr.repository.NodeRef downloadNodeRef)
    Read back the nodes to export, or an empty array if the download node doesn't carry any: the caller then falls back on the associations of the download request.

    storeNodes(org.alfresco.service.cmr.repository.ContentService contentService, org.alfresco.service.cmr.repository.NodeRef downloadNodeRef, List<org.alfresco.service.cmr.repository.NodeRef> nodeRefs)
    Store the nodes to export on the download node.

      private ExportSearchNodesHelper()

  • Method Details

    • storeNodes

      public static void storeNodes(org.alfresco.service.cmr.repository.ContentService contentService, org.alfresco.service.cmr.repository.NodeRef downloadNodeRef, List<org.alfresco.service.cmr.repository.NodeRef> nodeRefs)

      Store the nodes to export on the download node.

      Parameters:
      contentService - a ContentService object
      downloadNodeRef - a NodeRef object
      nodeRefs - a List object

    • readNodes

      public static org.alfresco.service.cmr.repository.NodeRef[] readNodes(org.alfresco.service.cmr.repository.ContentService contentService, org.alfresco.service.cmr.repository.NodeService nodeService, org.alfresco.service.cmr.repository.NodeRef downloadNodeRef)

      Read back the nodes to export, or an empty array if the download node doesn't carry any: the caller then falls back on the associations of the download request.

      A node deleted between the search and the asynchronous export is left out: the exporter would fail on it and lose the whole archive, whereas it is simply out of scope.

      Parameters:
      contentService - a ContentService object
      nodeService - a NodeService object
      downloadNodeRef - a NodeRef object
      Returns:
      an array of NodeRef objects
