Example 1 with BaseMapColumnState

use of org.apache.drill.exec.physical.rowSet.impl.ColumnState.BaseMapColumnState in project drill by axbaretto.

the class TupleState method buildSchema.

/**
 * When creating a schema up front, provide the schema of the desired tuple,
 * then build vectors and writers to match. Allows up-front schema definition
 * in addition to on-the-fly schema creation handled elsewhere.
 *
 * @param schema desired tuple schema to be materialized
