枚举 ObjectMapper.DefaultTyping

java.lang.Object

java.lang.Enum<ObjectMapper.DefaultTyping>

org.codehaus.jackson.map.ObjectMapper.DefaultTyping

所有已实现的接口:

Serializable, Comparable<ObjectMapper.DefaultTyping>

封闭类:

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.

从以下版本开始:

1.5

枚举常量概要

枚举常量

枚举常量和说明
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).

枚举常量详细资料

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.

方法详细资料

values

public static ObjectMapper.DefaultTyping[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (ObjectMapper.DefaultTyping c : ObjectMapper.DefaultTyping.values())
    System.out.println(c);

valueOf

public static ObjectMapper.DefaultTyping valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

如果该枚举类型没有带有指定名称的常量, - 则抛出 IllegalArgumentException

如果参数为空值, - 则抛出 NullPointerException
