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
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.

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 Maps, 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 Collections and Maps, method isEmpty() is called;
• For Java arrays, empty arrays are ones with length of 0
• For Java Strings, 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.

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
