Examples with MapData org.apache.flink.table.data.MapData used on opensource projects

Example 1 with MapData

use of org.apache.flink.table.data.MapData in project flink by apache.

the class RowDataToAvroConverters method createMapConverter.

private static RowDataToAvroConverter createMapConverter(LogicalType type) {
    LogicalType valueType = extractValueTypeToAvroMap(type);
    final ArrayData.ElementGetter valueGetter = ArrayData.createElementGetter(valueType);
    final RowDataToAvroConverter valueConverter = createConverter(valueType);
    return new RowDataToAvroConverter() {

        private static final long serialVersionUID = 1L;

        @Override
        public Object convert(Schema schema, Object object) {
            final Schema valueSchema = schema.getValueType();
            final MapData mapData = (MapData) object;
            final ArrayData keyArray = mapData.keyArray();
            final ArrayData valueArray = mapData.valueArray();
            final Map<Object, Object> map = new HashMap<>(mapData.size());
            for (int i = 0; i < mapData.size(); ++i) {
                final String key = keyArray.getString(i).toString();
                final Object value = valueConverter.convert(valueSchema, valueGetter.getElementOrNull(valueArray, i));
                map.put(key, value);
            }
            return map;
        }
    };
}

Example 2 with MapData

use of org.apache.flink.table.data.MapData in project flink by apache.

the class RowDataVectorizer method setColumn.

private static void setColumn(int rowId, MapColumnVector mapColumnVector, LogicalType type, RowData row, int columnId) {
    MapData mapData = row.getMap(columnId);
    MapType mapType = (MapType) type;
    ArrayData keyArray = mapData.keyArray();
    ArrayData valueArray = mapData.valueArray();
    mapColumnVector.lengths[rowId] = mapData.size();
    mapColumnVector.offsets[rowId] = mapColumnVector.childCount;
    mapColumnVector.childCount += mapColumnVector.lengths[rowId];
    mapColumnVector.keys.ensureSize(mapColumnVector.childCount, mapColumnVector.offsets[rowId] != 0);
    mapColumnVector.values.ensureSize(mapColumnVector.childCount, mapColumnVector.offsets[rowId] != 0);
    RowData convertedKeyRowData = convert(keyArray, mapType.getKeyType());
    RowData convertedValueRowData = convert(valueArray, mapType.getValueType());
    for (int i = 0; i < keyArray.size(); i++) {
        setColumn((int) mapColumnVector.offsets[rowId] + i, mapColumnVector.keys, mapType.getKeyType(), convertedKeyRowData, i);
        setColumn((int) mapColumnVector.offsets[rowId] + i, mapColumnVector.values, mapType.getValueType(), convertedValueRowData, i);
    }
}

Example 3 with MapData

use of org.apache.flink.table.data.MapData in project flink by apache.

the class MapDataSerializerTest method getTestData.

@Override
protected MapData[] getTestData() {
    Map<Object, Object> first = new HashMap<>();
    first.put(1L, -100.1F);
    BinaryArrayData keyBinary = BinaryArrayData.fromPrimitiveArray(new long[] { 10L, 20L });
    BinaryArrayData valueBinary = new BinaryArrayData();
    BinaryArrayWriter writer = new BinaryArrayWriter(valueBinary, 2, 4);
    BinaryArrayWriter.NullSetter nullSetter = BinaryArrayWriter.createNullSetter(FLOAT);
    writer.writeFloat(0, 10.2F);
    nullSetter.setNull(writer, 1);
    writer.complete();
    return new MapData[] { new GenericMapData(first), BinaryMapData.valueOf(keyBinary, valueBinary) };
}
