Enum EnumFeature

java.lang.Object
java.lang.Enum<EnumFeature>
com.fasterxml.jackson.databind.cfg.EnumFeature
All Implemented Interfaces:
com.fasterxml.jackson.core.util.JacksonFeature, DatatypeFeature, Serializable, Comparable<EnumFeature>, java.lang.constant.Constable

public enum EnumFeature extends Enum<EnumFeature> implements DatatypeFeature
New Datatype-specific configuration options related to handling of Enum types.
Since:
2.14
  • Enum Constant Details

    • READ_ENUM_KEYS_USING_INDEX

      public static final EnumFeature READ_ENUM_KEYS_USING_INDEX
      Feature that determines standard deserialization mechanism used for Enum values: if enabled, Enums are assumed to have been serialized using index of Enum;

      Note: this feature should be symmetric to as SerializationFeature.WRITE_ENUM_KEYS_USING_INDEX.

      Feature is disabled by default.

      Since:
      2.15
    • WRITE_ENUMS_TO_LOWERCASE

      public static final EnumFeature WRITE_ENUMS_TO_LOWERCASE
      Feature that determines standard serialization mechanism used for Enum values: if enabled, return value of Enum.name().toLowerCase() is used; if disabled, return value of Enum.name() is used.

      NOTE: this feature CAN NOT be changed on per-call basis: it will have to be set on ObjectMapper before use

      Feature is disabled by default.

      Since:
      2.15
  • Method Details

    • values

      public static EnumFeature[] 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 EnumFeature 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
