question: public boolean contains ( List < Integer > hashes ) { Iterator < Integer > ni = hashes . iterator ( ) ; for ( int i = 0 ; i < hashFunctions ; ++ i ) { if ( ! testBit ( ( int ) ( ( ni . next ( ) & 0xFFFFFFFFL ) % ( filter . length * 8 ) ) ) ) { return false ; } } return true ; }
target:  check if the filter contains data with precomputed hashes.
