Enum JsonFormat.Feature

  • All Implemented Interfaces:
    Serializable, Comparable<JsonFormat.Feature>
    Enclosing class:
    JsonFormat

    public static enum JsonFormat.Feature
extends Enum<JsonFormat.Feature>
    Set of features that can be enabled/disabled for property annotated. These often relate to specific SerializationFeature or DeserializationFeature, as noted by entries.

    Note that whether specific setting has an effect depends on whether JsonSerializer / JsonDeserializer being used takes the format setting into account. If not, please file an issue for adding support via issue tracker for package that has handlers (if you know which one; if not, just use `jackson-databind`).

    Since:
    2.6

    • Enum Constant Detail

      • ACCEPT_SINGLE_VALUE_AS_ARRAY

        public static final JsonFormat.Feature ACCEPT_SINGLE_VALUE_AS_ARRAY
        Override for DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY which will allow deserialization of JSON non-array values into single-element Java arrays and Collections.

      • ACCEPT_CASE_INSENSITIVE_PROPERTIES

        public static final JsonFormat.Feature ACCEPT_CASE_INSENSITIVE_PROPERTIES
        Override for MapperFeature.ACCEPT_CASE_INSENSITIVE_PROPERTIES. Only affects deserialization, has no effect on serialization.
        Since:
        2.8

      • WRITE_DATE_TIMESTAMPS_AS_NANOSECONDS

        public static final JsonFormat.Feature WRITE_DATE_TIMESTAMPS_AS_NANOSECONDS
        Override for SerializationFeature.WRITE_DATE_TIMESTAMPS_AS_NANOSECONDS, similar constraints apply.

      • WRITE_DATES_WITH_ZONE_ID

        public static final JsonFormat.Feature WRITE_DATES_WITH_ZONE_ID
        Override for SerializationFeature.WRITE_DATES_WITH_ZONE_ID, similar constraints apply.

      • WRITE_SINGLE_ELEM_ARRAYS_UNWRAPPED

        public static final JsonFormat.Feature WRITE_SINGLE_ELEM_ARRAYS_UNWRAPPED
        Override for SerializationFeature.WRITE_SINGLE_ELEM_ARRAYS_UNWRAPPED which will force serialization of single-element arrays and Collections as that single element and excluding array wrapper.

      • WRITE_SORTED_MAP_ENTRIES

        public static final JsonFormat.Feature WRITE_SORTED_MAP_ENTRIES
        Override for SerializationFeature.ORDER_MAP_ENTRIES_BY_KEYS, enabling of which will force sorting of Map keys before serialization.

      • ADJUST_DATES_TO_CONTEXT_TIME_ZONE

        public static final JsonFormat.Feature ADJUST_DATES_TO_CONTEXT_TIME_ZONE
        Override for DeserializationFeature.ADJUST_DATES_TO_CONTEXT_TIMEZONE that specifies whether context provided timezone DeserializationContext.getTimeZone() should be used to adjust Date/Time values on deserialization, even if value itself contains timezone information
        Since:
        2.8

    • Method Detail

      • values

        public static JsonFormat.Feature[] 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 (JsonFormat.Feature c : JsonFormat.Feature.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static JsonFormat.Feature 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
