## Enum JsonSerialize.Inclusion

- java.lang.Object
- - java.lang.Enum<JsonSerialize.Inclusion>
  - - com.fasterxml.jackson.databind.annotation.JsonSerialize.Inclusion

- All Implemented Interfaces:
    Serializable, Comparable<JsonSerialize.Inclusion>
  Enclosing class:
    JsonSerialize

      public static enum JsonSerialize.Inclusion
      extends Enum<JsonSerialize.Inclusion>

  Enumeration used with `JsonSerialize.include()` property to define which properties of Java Beans are to be included in serialization

- - ### Enum Constant Summary

    Enum Constants
    Enum Constant and Description
    `ALWAYS` Value that indicates that properties are to be always included, independent of value
    `DEFAULT_INCLUSION` Pseudo-value that is used to indicate "use whatever is default used at higher level".
    `NON_DEFAULT` Value that indicates that only properties that have values that differ from default settings (meaning values they have when Bean is constructed with its no-arguments constructor) are to be included.
    `NON_EMPTY` Value that indicates that only properties that have values that values that are null or what is considered empty are not to be included.
    `NON_NULL` Value that indicates that only properties with non-null values are to be included.

  - ### Method Summary

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `static JsonSerialize.Inclusion` | `valueOf(String name)` Returns the enum constant of this type with the specified name.
    `static JsonSerialize.Inclusion[]` | `values()` Returns an array containing the constants of this enum type, in the order they are declared.

- - ### Enum Constant Detail

    - #### ALWAYS

          public static final JsonSerialize.Inclusion ALWAYS

      Value that indicates that properties are to be always included, independent of value

    - #### NON_NULL

          public static final JsonSerialize.Inclusion NON_NULL

      Value that indicates that only properties with non-null values are to be included.

    - #### NON_DEFAULT

          public static final JsonSerialize.Inclusion NON_DEFAULT

      Value that indicates that only properties that have values that differ from default settings (meaning values they have when Bean is constructed with its no-arguments constructor) are to be included. Value is generally not useful with `Map`s, since they have no default values; and if used, works same as `ALWAYS`.

    - #### NON_EMPTY

          public static final JsonSerialize.Inclusion NON_EMPTY

      Value that indicates that only properties that have values that values that are null or what is considered empty are not to be included. Emptiness is defined for following type:
      - For `Collection`s and `Map`s, method `isEmpty()` is called;
      - For Java arrays, empty arrays are ones with length of 0
      - For Java `String`s, `length()` is called, and return value of 0 indicates empty String (note that `String.isEmpty()` was added in Java 1.6 and as such can not be used by Jackson
      For other types, non-null values are to be included.

    - #### DEFAULT_INCLUSION

          public static final JsonSerialize.Inclusion DEFAULT_INCLUSION

      Pseudo-value that is used to indicate "use whatever is default used at higher level".
      Since:
        2.3

  - ### Method Detail

    - #### values

          public static JsonSerialize.Inclusion[] 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 (JsonSerialize.Inclusion c : JsonSerialize.Inclusion.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static JsonSerialize.Inclusion 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
