Example 21 with MapValue

use of io.questdb.cairo.map.MapValue in project questdb by bluestreak01.

the class SampleByFillPrevRecordCursor method toTop.

@Override
public void toTop() {
    super.toTop();
    if (base.hasNext()) {
        baseRecord = base.getRecord();
        int n = groupByFunctions.size();
        RecordCursor mapCursor = map.getCursor();
        MapRecord mapRecord = map.getRecord();
        while (mapCursor.hasNext()) {
            MapValue value = mapRecord.getValue();
            // timestamp is always stored in value field 0
            value.putLong(0, Numbers.LONG_NaN);
            // this would set values for when keys are not found right away
            for (int i = 0; i < n; i++) {
                groupByFunctions.getQuick(i).setNull(value);
            }
        }
    }
