- com.fasterxml.jackson.annotation.JsonSetter.Value

All Implemented Interfaces:

JacksonAnnotationValue<JsonSetter>, Serializable

Enclosing class:

JsonSetter
```
public static class JsonSetter.Value
extends Object
implements JacksonAnnotationValue<JsonSetter>, Serializable
```
Helper class used to contain information from a single JsonSetter annotation, as well as to provide possible overrides from non-annotation sources.

Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`static JsonSetter.Value`	`construct(Nulls nulls, Nulls contentNulls)` Factory method that may be used (although is NOT the recommended way) to construct an instance from a full set of properties.
`static JsonSetter.Value`	`empty()` Accessor for default instances which has "empty" settings; that is: Null handling using global defaults, `Nulls.DEFAULT`.
`boolean`	`equals(Object o)`
`static JsonSetter.Value`	`forContentNulls(Nulls nulls)`
`static JsonSetter.Value`	`forValueNulls(Nulls nulls)`
`static JsonSetter.Value`	`forValueNulls(Nulls nulls, Nulls contentNulls)`
`static JsonSetter.Value`	`from(JsonSetter src)`
`Nulls`	`getContentNulls()`
`Nulls`	`getValueNulls()`
`int`	`hashCode()`
`static JsonSetter.Value`	`merge(JsonSetter.Value base, JsonSetter.Value overrides)` Helper method that will try to combine values from two `JsonSetter.Value` instances, using one as base settings, and the other as overrides to use instead of base values when defined; base values are only use if override does not specify a value (matching value is null or logically missing).
`Nulls`	`nonDefaultContentNulls()` Returns same as `getContentNulls()` unless value would be `Nulls.DEFAULT` in which case `null` is returned.
`Nulls`	`nonDefaultValueNulls()` Returns same as `getValueNulls()` unless value would be `Nulls.DEFAULT` in which case `null` is returned.
`protected Object`	`readResolve()`
`String`	`toString()`
`Class<JsonSetter>`	`valueFor()` Introspection method that may be used to find actual annotation that may be used as the source for value instance.
`JsonSetter.Value`	`withContentNulls(Nulls nulls)`
`JsonSetter.Value`	`withOverrides(JsonSetter.Value overrides)` Mutant factory method that merges values of this value with given override values, so that any explicitly defined inclusion in overrides has precedence over settings of this value instance.
`JsonSetter.Value`	`withValueNulls(Nulls nulls)`
`JsonSetter.Value`	`withValueNulls(Nulls valueNulls, Nulls contentNulls)`

```
- Method Detail
  - valueFor
```
public Class<JsonSetter> valueFor()
```
    Description copied from interface: JacksonAnnotationValue
    
    Introspection method that may be used to find actual annotation that may be used as the source for value instance.
    
    Specified by:
    
    valueFor in interface JacksonAnnotationValue<JsonSetter>
    
    Returns:
    
    Annotation class for which instances of this value class are created
  - readResolve
```
protected Object readResolve()
```
  - from
```
public static JsonSetter.Value from(JsonSetter src)
```
  - construct
```
public static JsonSetter.Value construct(Nulls nulls,
                                         Nulls contentNulls)
```
    Factory method that may be used (although is NOT the recommended way) to construct an instance from a full set of properties. Most users would be better of starting by empty() instance and using `withXxx`/`withoutXxx` methods, as this factory method may need to be changed if new properties are added in JsonIgnoreProperties annotation.
  - empty
```
public static JsonSetter.Value empty()
```
    Accessor for default instances which has "empty" settings; that is:
    - Null handling using global defaults, Nulls.DEFAULT.
  - merge
```
public static JsonSetter.Value merge(JsonSetter.Value base,
                                     JsonSetter.Value overrides)
```
    Helper method that will try to combine values from two JsonSetter.Value instances, using one as base settings, and the other as overrides to use instead of base values when defined; base values are only use if override does not specify a value (matching value is null or logically missing). Note that one or both of value instances may be `null`, directly; if both are `null`, result will also be `null`; otherwise never null.
  - forValueNulls
```
public static JsonSetter.Value forValueNulls(Nulls nulls)
```
  - forValueNulls
```
public static JsonSetter.Value forValueNulls(Nulls nulls,
                                             Nulls contentNulls)
```
  - forContentNulls
```
public static JsonSetter.Value forContentNulls(Nulls nulls)
```
  - withOverrides
```
public JsonSetter.Value withOverrides(JsonSetter.Value overrides)
```
    Mutant factory method that merges values of this value with given override values, so that any explicitly defined inclusion in overrides has precedence over settings of this value instance. If no overrides exist will return this instance; otherwise new JsonSetter.Value with changed inclusion values.
  - withValueNulls
```
public JsonSetter.Value withValueNulls(Nulls nulls)
```
  - withValueNulls
```
public JsonSetter.Value withValueNulls(Nulls valueNulls,
                                       Nulls contentNulls)
```
  - withContentNulls
```
public JsonSetter.Value withContentNulls(Nulls nulls)
```
  - getValueNulls
```
public Nulls getValueNulls()
```
  - getContentNulls
```
public Nulls getContentNulls()
```
  - nonDefaultValueNulls
```
public Nulls nonDefaultValueNulls()
```
    Returns same as getValueNulls() unless value would be Nulls.DEFAULT in which case `null` is returned.
  - nonDefaultContentNulls
```
public Nulls nonDefaultContentNulls()
```
    Returns same as getContentNulls() unless value would be Nulls.DEFAULT in which case `null` is returned.
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - equals
```
public boolean equals(Object o)
```
    Overrides:
    
    equals in class Object
