public enum NullOrder
extends Enum<NullOrder>

(experimental) Null ordering values for Iceberg sort fields.

Example:

 // Build a table with partition spec, sort order, and table properties
 Table advancedTable = Table.Builder.create(scope, "AdvancedTable")
         .tableName("advanced_table")
         .namespace(namespace)
         .openTableFormat(OpenTableFormat.ICEBERG)

                         .build())
                 .icebergPartitionSpec(IcebergPartitionSpec.builder()
                         .specId(0)

                                 .name("date_partition")

                                 .build()))
                         .build())
                 .tableProperties(List.of(TablePropertyEntry.builder().key("write.format.default").value("parquet").build()))

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static NullOrder valueOf(String name)
