+ * Details Regarding Data Structure of ExportObjects: + * + *

    + *
  • The exportMap map, exportListeners list, exportListenerVersion, and export object's exportListenerVersion work + * together to enable a listener to synchronize with outstanding exports in addition to sending the listener updates + * while they continue to subscribe.
    • + * + *
  • SessionState::exportMap's purpose is to map from the export id to the export object
    • + *
  • SessionState::exportListeners' purpose is to keep a list of active subscribers
    • + *
  • SessionState::exportListenerVersion's purpose is to know whether or not a subscriber has already seen a + * status
    • + * + *
  • A listener will receive an export notification for export id NON_EXPORT_ID (a zero) to indicate that the run has + * completed. A listener may see an update for an export before receiving the "run has completed" message. A listener + * should be prepared to receive duplicate/redundant updates.
