@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.

values
public static ExtractionVersion[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (ExtractionVersion c : ExtractionVersion.values()) System.out.println(c);
- 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 nameNullPointerException
- if the argument is null
