ObjectMapper.DefaultTyping (jackson-databind 2.9.9.2)

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.
Since 2.4 there are special exceptions for JSON Tree model types (sub-types of TreeNode: default typing is never applied to them. Since 2.8(.4) additional checks are made to avoid attempts at default typing primitive-valued properties.
NOTE: use of Default Typing can be a potential security risk if incoming content comes from untrusted sources, and it is recommended that this is either not done, or, if enabled, use ObjectMapper.setDefaultTyping(com.fasterxml.jackson.databind.jsontype.TypeResolverBuilder<?>) passing a custom TypeResolverBuilder implementation that white-lists legal types to use.

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.
    Since 2.4, this does NOT apply to TreeNode and its subtypes.
  - 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.
    Since 2.4, this does NOT apply to TreeNode and its subtypes.
  - 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.
    Since 2.4, this does NOT apply to TreeNode and its subtypes.

```
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
