use of org.apache.drill.exec.vector.accessor.writer.AbstractTupleWriter.TupleObjectWriter in project drill by axbaretto.

the class ColumnWriterFactory method buildMapArray.

public static ArrayObjectWriter buildMapArray(ColumnMetadata schema, UInt4Vector offsetVector, List<AbstractObjectWriter> writers) {
    MapWriter mapWriter;
    if (schema.isProjected()) {
        mapWriter = new ArrayMapWriter(schema, writers);

        mapWriter = new DummyArrayMapWriter(schema, writers);
    }
    TupleObjectWriter mapArray = new TupleObjectWriter(schema, mapWriter);
    AbstractArrayWriter arrayWriter;
    if (schema.isProjected()) {
        arrayWriter = new ObjectArrayWriter(offsetVector, mapArray);
    } else {
        arrayWriter = new DummyArrayWriter(mapArray);
    }
    return new ArrayObjectWriter(schema, arrayWriter);
}

Example 2 with TupleObjectWriter

use of org.apache.drill.exec.vector.accessor.writer.AbstractTupleWriter.TupleObjectWriter in project drill by apache.

the class ColumnBuilder method buildSingleMap.

private ColumnState buildSingleMap(ContainerState parent, ColumnMetadata columnSchema) {
    final ProjectionFilter projFilter = parent.projection();
    final ProjResult projResult = projFilter.projection(columnSchema);
    final MapVector vector;
    final VectorState vectorState;
    if (projResult.isProjected) {
        // vectors can be cached.
        assert columnSchema.tupleSchema().isEmpty();
        vector = new MapVector(columnSchema.schema(), parent.loader().allocator(), null);
        vectorState = new MapVectorState(vector, new NullVectorState());
    } else {
        vector = null;

    }
    final TupleObjectWriter mapWriter = MapWriter.buildMap(columnSchema, vector, new ArrayList<>());
    final SingleMapState mapState = new SingleMapState(parent.loader(), parent.vectorCache().childCache(columnSchema.name()), projResult.mapFilter);
    return new MapColumnState(mapState, mapWriter, vectorState, parent.isVersioned());
