question: private void processInitiators ( List < String > initiatorNames , Map < URI , Set < URI > > hostToInitiatorMap ) { for ( String initiatorWWNStr : initiatorNames ) { Initiator initiator = fetchInitiatorByName ( initiatorWWNStr ) ; if ( null != initiator ) { Set < URI > initiators = hostToInitiatorMap . get ( initiator . getHost ( ) ) ; if ( initiators == null ) { initiators = new HashSet < URI > ( ) ; hostToInitiatorMap . put ( initiator . getHost ( ) , initiators ) ; } initiators . add ( initiator . getId ( ) ) ; } } }
target:  Process the initiators passed in to form a host => initiators data structure.
