Enum PropertyAccessor

java.lang.Object

java.lang.Enum<PropertyAccessor>

com.fasterxml.jackson.annotation.PropertyAccessor

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<PropertyAccessor>

public enum PropertyAccessor
extends java.lang.Enum<PropertyAccessor>

Enumeration used to define kinds of elements (called "property accessors") that annotations like JsonAutoDetect apply to.

In addition to method types (GETTER/IS_GETTER, SETTER, CREATOR) and the field type (FIELD), 2 pseudo-types are defined for convenience: ALWAYS and NONE. These can be used to indicate, all or none of available method types (respectively), for use by annotations that takes JsonMethod argument.

Enum Constant Summary

Enum Constants

Enum Constant and Description
ALL This pseudo-type indicates that all accessors are affected.
CREATOR Creators are constructors and (static) factory methods used to construct POJO instances for deserialization
FIELD Field refers to fields of regular Java objects.
GETTER Getters are methods used to get a POJO field value for serialization, or, under certain conditions also for de-serialization.
IS_GETTER "Is getters" are getter-like methods that are named "isXxx" (instead of "getXxx" for getters) and return boolean value (either primitive, or Boolean).
NONE This pseudo-type indicates that none of accessors if affected.
SETTER Setters are methods used to set a POJO value for deserialization.

Enum Constant Detail

GETTER

public static final PropertyAccessor GETTER

Getters are methods used to get a POJO field value for serialization, or, under certain conditions also for de-serialization. Latter can be used for effectively setting Collection or Map values in absence of setters, iff returned value is not a copy but actual value of the logical property.

Since version 1.3, this does NOT include "is getters" (methods that return boolean and named 'isXxx' for property 'xxx'); instead, IS_GETTER is used}.

SETTER

public static final PropertyAccessor SETTER

Setters are methods used to set a POJO value for deserialization.

CREATOR

public static final PropertyAccessor CREATOR

Creators are constructors and (static) factory methods used to construct POJO instances for deserialization

FIELD

public static final PropertyAccessor FIELD

Field refers to fields of regular Java objects. Although they are not really methods, addition of optional field-discovery in version 1.1 meant that there was need to enable/disable their auto-detection, and this is the place to add it in.

IS_GETTER

public static final PropertyAccessor IS_GETTER

"Is getters" are getter-like methods that are named "isXxx" (instead of "getXxx" for getters) and return boolean value (either primitive, or Boolean).

NONE

public static final PropertyAccessor NONE

This pseudo-type indicates that none of accessors if affected.

ALL

public static final PropertyAccessor ALL

This pseudo-type indicates that all accessors are affected.

Method Detail

values

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

Returns:

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

valueOf

public static PropertyAccessor valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
