Example 7 with AbstractMapVector

use of org.apache.drill.exec.vector.complex.AbstractMapVector in project drill by apache.

the class BuildVectorsFromMetadata method buildMap.

/**
 * Build a map column including the members of the map given a map
 * column schema.
 *
 * @param schema the schema of the map column
 * @return the completed map vector column model
 */
private AbstractMapVector buildMap(ColumnMetadata schema) {
    // Creating the map vector will create its contained vectors if we
    // give it a materialized field with children. So, instead pass a clone
    // without children so we can add the children as we add vectors.
    final AbstractMapVector mapVector = (AbstractMapVector) TypeHelper.getNewVector(schema.emptySchema(), allocator, null);
    populateMap(mapVector, schema.tupleSchema(), false);
    return mapVector;
