Description

currently, we have RowToColumnConverter for all data types except AnsiIntervalType

// code placeholder
val core = dataType match {
  case BinaryType => BinaryConverter
  case BooleanType => BooleanConverter
  case ByteType => ByteConverter
  case ShortType => ShortConverter
  case IntegerType | DateType => IntConverter
  case FloatType => FloatConverter
  case LongType | TimestampType => LongConverter
  case DoubleType => DoubleConverter
  case StringType => StringConverter
  case CalendarIntervalType => CalendarConverter
  case at: ArrayType => ArrayConverter(getConverterForType(at.elementType, at.containsNull))
  case st: StructType => new StructConverter(st.fields.map(
    (f) => getConverterForType(f.dataType, f.nullable)))
  case dt: DecimalType => new DecimalConverter(dt)
  case mt: MapType => MapConverter(getConverterForType(mt.keyType, nullable = false),
    getConverterForType(mt.valueType, mt.valueContainsNull))
  case unknown => throw QueryExecutionErrors.unsupportedDataTypeError(unknown.toString)
}

if (nullable) {
  dataType match {
    case CalendarIntervalType => new StructNullableTypeConverter(core)
    case st: StructType => new StructNullableTypeConverter(core)
    case _ => new BasicNullableTypeConverter(core)
  }
} else {
  core
}
