org.hsqldb_voltpatches.index.Index.compareRowNonUnique()
Compares two table rows based on the columns of this index. The rowColMap parameter specifies which columns of the other table are to be compared with the colIndex columns of this index. The rowColMap can cover all or only some columns of this index. @param a row from another table @param rowColMap column indexes in the other table @param b a full row in this table @return comparison result, -1,0,+1

                // walk the index for all the nodes that reference delnode
                for (;;) {
                    Row refrow = refiterator.getNextRow();


                    if (refrow == null || refrow.isDeleted(session)
                            || refindex.compareRowNonUnique(
                                mdata, m_columns, refrow.getData()) != 0) {
                        break;
                    }


                    // -- if the constraint is a 'SET [DEFAULT|NULL]' constraint we have to keep
