Field Detail

USE_LEGACY_TO_STRING

public static boolean USE_LEGACY_TO_STRING

Internal flag to enable the legacy Row.toString() implementation for tests. In general, tests should not depend on the string representation of rows but should fully compare instances (especially data types of fields). This flag will be dropped once all tests have been updated.

Method Detail

compareRows

public static boolean compareRows(List<Row> l1,
                                  List<Row> l2)

Compares two Lists of Row for deep equality. This method supports all conversion classes of the table ecosystem.

compareRows

public static boolean compareRows(List<Row> l1,
                                  List<Row> l2,
                                  boolean ignoreOrder)

Compares two Lists of Row for deep equality. This method supports all conversion classes of the table ecosystem. The top-level lists can be compared with or without order.

createRowWithNamedPositions

@Internal
public static Row createRowWithNamedPositions(RowKind kind,
                                              Object[] fieldByPosition,
                                              LinkedHashMap<String,Integer> positionByName)

Internal utility for creating a row in static named-position field mode.
