public class TestVariantAccessors
extends SubOperatorTest

Tests for readers and writers for union and list types.

Note that the union type is only partially supported in Drill. The list type is unsupported. (However, the list type works in the schema builder, row set writer, row set reader and the result set builder. It does not, however, work in the Project and other operators. Some assembly required for future use.)

Method Detail

testBuildRowSetUnion

public void testBuildRowSetUnion()

testScalarVariant

public void testScalarVariant()

Test a variant (AKA "union vector") at the top level, using just scalar values.

testBuildRowSetScalarList

public void testBuildRowSetScalarList()

testBuildRowSetUnionArray

public void testBuildRowSetUnionArray()

testUnionWithMap

public void testUnionWithMap()

Test a variant (AKA "union vector") at the top level which includes a map.

testScalarList

public void testScalarList()

Test a scalar list. Should act just like a repeated type, with the addition of allowing the list for a row to be null. But, a list writer does not do auto-increment, so we must do that explicitly after each write.

testListOfMaps

public void testListOfMaps()

List of maps. Like a repeated map, but each list entry can be null.

testListOfUnions

public void testListOfUnions()

Test a union list.

testAddTypes

public void testAddTypes()

Test a variant (AKA "union vector") at the top level, using just scalar values.

testUnionWithList

public void testUnionWithList()

Test a variant (AKA "union vector") at the top level which includes a list.
