Enum JsonFormat.Feature

java.lang.Object

java.lang.Enum<JsonFormat.Feature>

com.fasterxml.jackson.annotation.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 Summary

Enum Constants

Enum Constant and Description
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.
WRITE_DATE_TIMESTAMPS_AS_NANOSECONDS Override for SerializationFeature.WRITE_DATE_TIMESTAMPS_AS_NANOSECONDS, similar constraints apply.
WRITE_DATES_WITH_ZONE_ID Override for SerializationFeature.WRITE_DATES_WITH_ZONE_ID, similar constraints apply.
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 Override for SerializationFeature.ORDER_MAP_ENTRIES_BY_KEYS, enabling of which will force sorting of Map keys before serialization.

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.

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
