question: private void fetchFilterSeeds ( ) { if ( seedList == null || seedList . isEmpty ( ) ) { return ; } for ( Iterator < URI > it = seedList . iterator ( ) ; it . hasNext ( ) ; ) { URI seed = it . next ( ) ; for ( FetchFilter filter : controller . getFetchFilters ( ) ) { FetchStatus filterReason = filter . checkFilter ( seed ) ; if ( filterReason != FetchStatus . VALID ) { if ( log . isDebugEnabled ( ) ) { log . debug ( "Seed: " + seed + " was filtered with reason: " + filterReason ) ; } it . remove ( ) ; break ; } } } }
target:  Filters the seed list using the current fetch filters, preventing any non-valid seed from being accessed.
