Enum ObjectMapper.DefaultTyping

java.lang.Object

java.lang.Enum<ObjectMapper.DefaultTyping>

com.fasterxml.jackson.databind.ObjectMapper.DefaultTyping

All Implemented Interfaces:

Serializable, Comparable<ObjectMapper.DefaultTyping>

Enclosing class:

ObjectMapper

public static enum ObjectMapper.DefaultTyping
extends Enum<ObjectMapper.DefaultTyping>

Enumeration used with ObjectMapper.enableDefaultTyping() to specify what kind of types (classes) default typing should be used for. It will only be used if no explicit type information is found, but this enumeration further limits subset of those types.

Enum Constant Summary

Enum Constants

Enum Constant and Description
JAVA_LANG_OBJECT This value means that only properties that have Object as declared type (including generic types without explicit type) will use default typing.
NON_CONCRETE_AND_ARRAYS Value that means that default typing will be used for all types covered by OBJECT_AND_NON_CONCRETE plus all array types for them.
NON_FINAL Value that means that default typing will be used for all non-final types, with exception of small number of "natural" types (String, Boolean, Integer, Double), which can be correctly inferred from JSON; as well as for all arrays of non-final types.
OBJECT_AND_NON_CONCRETE Value that means that default typing will be used for properties with declared type of Object or an abstract type (abstract class or interface).

Enum Constant Detail

JAVA_LANG_OBJECT

public static final ObjectMapper.DefaultTyping JAVA_LANG_OBJECT

This value means that only properties that have Object as declared type (including generic types without explicit type) will use default typing.

OBJECT_AND_NON_CONCRETE

public static final ObjectMapper.DefaultTyping OBJECT_AND_NON_CONCRETE

Value that means that default typing will be used for properties with declared type of Object or an abstract type (abstract class or interface). Note that this does not include array types.

NON_CONCRETE_AND_ARRAYS

public static final ObjectMapper.DefaultTyping NON_CONCRETE_AND_ARRAYS

Value that means that default typing will be used for all types covered by OBJECT_AND_NON_CONCRETE plus all array types for them.

NON_FINAL

public static final ObjectMapper.DefaultTyping NON_FINAL

Value that means that default typing will be used for all non-final types, with exception of small number of "natural" types (String, Boolean, Integer, Double), which can be correctly inferred from JSON; as well as for all arrays of non-final types.

Method Detail

values

public static ObjectMapper.DefaultTyping[] 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 (ObjectMapper.DefaultTyping c : ObjectMapper.DefaultTyping.values())
    System.out.println(c);

Returns:

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

valueOf

public static ObjectMapper.DefaultTyping 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
