Enum ExtractionVersion

All Implemented Interfaces:
Serializable, Comparable<ExtractionVersion>
@PublicEvolving public enum ExtractionVersion extends Enum<ExtractionVersion>
Logical version that describes the expected behavior of the reflection-based data type extraction.

This enumeration is meant for future backward compatibility. Whenever the extraction logic is changed, old function and structured type classes should still return the same data type as before when versioned accordingly.

  • Enum Constant Details

    • UNKNOWN

      public static final ExtractionVersion UNKNOWN
      Default if no version is specified.

    • V1

      public static final ExtractionVersion V1
      Initial reflection-based extraction logic according to FLIP-65.

  • Method Details

    • values

      public static ExtractionVersion[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared

    • valueOf

      public static ExtractionVersion valueOf(String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null
