question: private Map < URI , ExportMask > createExportMaskMap ( Set < URI > placedMasks ) { Map < URI , ExportMask > exportMaskMap = new HashMap < > ( ) ; Iterator < ExportMask > exportMaskIterator = dbClient . queryIterativeObjects ( ExportMask . class , placedMasks , true ) ; while ( exportMaskIterator . hasNext ( ) ) { ExportMask exportMask = exportMaskIterator . next ( ) ; exportMaskMap . put ( exportMask . getId ( ) , exportMask ) ; } return exportMaskMap ; }
target:  Given a set of ExportMask URIs, return a map of ExportMask URI to ExportMask object
