question: public static Map < URI , BlockObject > translateRPSnapshots ( DbClient dbClient , List < URI > volumeURIList ) { Map < URI , BlockObject > blockObjectCache = new HashMap < > ( ) ; for ( URI boURI : volumeURIList ) { BlockObject blockObject = Volume . fetchExportMaskBlockObject ( dbClient , boURI ) ; blockObjectCache . put ( blockObject . getId ( ) , blockObject ) ; } return blockObjectCache ; }
target:  Lookup all the BlockObjects from their URI that is passed in. If this is an RP BlockSnapshot, return the paraent VirtualVolume.
