Enum Class JsonTypeInfo.As

java.lang.Object
java.lang.Enum<JsonTypeInfo.As>
edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.annotation.JsonTypeInfo.As
All Implemented Interfaces:
Serializable, Comparable<JsonTypeInfo.As>, java.lang.constant.Constable
Enclosing class:
JsonTypeInfo
public static enum JsonTypeInfo.As extends Enum<JsonTypeInfo.As>
Definition of standard type inclusion mechanisms for type metadata. Used for standard metadata types, except for JsonTypeInfo.Id.NONE. May or may not be used for custom types (JsonTypeInfo.Id.CUSTOM).

  • Enum Constant Summary

    Enum Constants
    Enum Constant
    Description
    EXISTING_PROPERTY
    Inclusion mechanism similar to PROPERTY with respect to deserialization; but one that is produced by a "regular" accessible property during serialization.
    EXTERNAL_PROPERTY
    Inclusion mechanism similar to PROPERTY, except that property is included one-level higher in hierarchy, i.e.
    PROPERTY
    Inclusion mechanism that uses a single configurable property, included along with actual data (POJO properties) as a separate meta-property.
    WRAPPER_ARRAY
    Inclusion mechanism that wraps typed JSON value (POJO serialized as JSON) in a 2-element JSON array: first element is the serialized type identifier, and second element the serialized POJO as JSON Object.
    WRAPPER_OBJECT
    Inclusion mechanism that wraps typed JSON value (POJO serialized as JSON) in a JSON Object that has a single entry, where field name is serialized type identifier, and value is the actual JSON value.

    • PROPERTY

      public static final JsonTypeInfo.As PROPERTY
      Inclusion mechanism that uses a single configurable property, included along with actual data (POJO properties) as a separate meta-property.

      Default choice for inclusion.

    • WRAPPER_OBJECT

      public static final JsonTypeInfo.As WRAPPER_OBJECT
      Inclusion mechanism that wraps typed JSON value (POJO serialized as JSON) in a JSON Object that has a single entry, where field name is serialized type identifier, and value is the actual JSON value.

      Note: can only be used if type information can be serialized as String. This is true for standard type metadata types, but not necessarily for custom types.

    • WRAPPER_ARRAY

      public static final JsonTypeInfo.As WRAPPER_ARRAY
      Inclusion mechanism that wraps typed JSON value (POJO serialized as JSON) in a 2-element JSON array: first element is the serialized type identifier, and second element the serialized POJO as JSON Object.

    • EXTERNAL_PROPERTY

      public static final JsonTypeInfo.As EXTERNAL_PROPERTY
      Inclusion mechanism similar to PROPERTY, except that property is included one-level higher in hierarchy, i.e. as sibling property at same level as JSON Object to type. Note that this mechanism can only be used for properties, not for types (classes). Trying to use it for classes will result in inclusion strategy of basic PROPERTY instead.

      Note also that this mechanism can not be used for container values (arrays, Collections, Maps); it only works for scalar and POJO values.

    • EXISTING_PROPERTY

      public static final JsonTypeInfo.As EXISTING_PROPERTY
      Inclusion mechanism similar to PROPERTY with respect to deserialization; but one that is produced by a "regular" accessible property during serialization. This means that TypeSerializer will do nothing, and expects a property with defined name to be output using some other mechanism (like default POJO property serialization, or custom serializer).

      Note that this behavior is quite similar to that of using JsonTypeId annotation; except that here TypeSerializer is basically suppressed; whereas with JsonTypeId, output of regular property is suppressed. This mostly matters with respect to output order; this choice is the only way to ensure specific placement of type id during serialization.

      Since:
      2.3.0 but databind only since 2.5.0.

  • Method Details

    • values

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

    • valueOf

      public static JsonTypeInfo.As valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name
      NullPointerException - if the argument is null
