doUpdate()

bool FWLiteJobMetadataManager::doUpdate ( FWJobMetadataUpdateRequest *  request )

overridevirtual

This method inspects the currently opened TFile and for each branch containing products for which we can either build a TCollectionProxy or for which we have a specialized accessor, it registers it as a viewable item.

Implements FWJobMetadataManager.
