Example 1 with TRow

use of org.apache.hive.service.rpc.thrift.TRow in project hive by apache.

the class RowBasedSet method iterator.

@Override
public Iterator<Object[]> iterator() {
    return new Iterator<Object[]>() {

        final Iterator<TRow> iterator = rows.iterator();

        final Object[] convey = new Object[numColumns()];

        @Override
        public boolean hasNext() {
            return iterator.hasNext();
        }

        @Override
        public Object[] next() {
            TRow row = iterator.next();
            List<TColumnValue> values = row.getColVals();
            for (int i = 0; i < values.size(); i++) {
                convey[i] = ColumnValue.toColumnValue(values.get(i));
            }
            return convey;
        }

        @Override
        public void remove() {
            throw new UnsupportedOperationException("remove");
        }
    };
}

Example 2 with TRow

use of org.apache.hive.service.rpc.thrift.TRow in project hive by apache.

@Override
public RowBasedSet addRow(Object[] fields) {
    TRow tRow = new TRow();
    for (int i = 0; i < fields.length; i++) {
        tRow.addToColVals(ColumnValue.toTColumnValue(descriptors[i], fields[i]));
    }
    rows.add(tRow);
    return this;
}

    } else {
        for (int i = 0; i < columns.size(); i++) {
            tRowSet.addToColumns(columns.get(i).toTColumn());
        }
    }
    return tRowSet;
