question: private boolean initializeSearchItemset ( BitVector bv , int [ ] scratchi , int [ ] iters ) { for ( int i = 0 ; i < scratchi . length ; i ++ ) { iters [ i ] = ( i == 0 ) ? bv . iter ( ) : bv . iterAdvance ( iters [ i - 1 ] ) ; if ( iters [ i ] < 0 ) { return false ; } scratchi [ i ] = bv . iterDim ( iters [ i ] ) ; } return true ; }
target:  Initialize the scratch itemset.
