## Annotation Type JsonSerialize

-     @Target(value={METHOD,FIELD,TYPE,PARAMETER})
      @Retention(value=RUNTIME)
      public @interface JsonSerialize

  Annotation used for configuring serialization aspects, by attaching to "getter" methods or fields, or to value classes. When annotating value classes, configuration is used for instances of the value class but can be overridden by more specific annotations (ones that attach to methods or fields).

  An example annotation would be:

        @JsonSerialize(using=MySerializer.class,
          as=MySubClass.class,
          include=JsonSerialize.Inclusion.NON_NULL,
          typing=JsonSerialize.Typing.STATIC
        )

  (which would be redundant, since some properties block others: specifically, 'using' has precedence over 'as', which has precedence over 'typing' setting)

  NOTE: since version 1.2, annotation has also been applicable to (constructor) parameters

  Since:
    1.1

    Optional Elements
    Modifier and Type | Optional Element and Description
    --- | ---
    `Class<?>` | `as` Supertype (of declared type, which itself is supertype of runtime type) to use as type when locating serializer to use.
    `Class<?>` | `contentAs` Concrete type to serialize content value (elements of a Collection/array, values of Maps) as, instead of type otherwise declared.
    `Class<? extends JsonSerializer<?>>` | `contentUsing` Serializer class to use for serializing contents (elements of a Collection/array, values of Maps) of annotated property.
    `JsonSerialize.Inclusion` | `include` Which properties of annotated Bean are to be included in serialization (has no effect on other types like enums, primitives or collections).
    `Class<?>` | `keyAs` Concrete type to serialize keys of `Map` as, instead of type otherwise declared.
    `Class<? extends JsonSerializer<?>>` | `keyUsing` Serializer class to use for serializing Map keys of annotated property.
    `JsonSerialize.Typing` | `typing` Whether type detection used is dynamic or static: that is, whether actual runtime type is used (dynamic), or just the declared type (static).
    `Class<? extends JsonSerializer<?>>` | `using` Serializer class to use for serializing associated value.

- - ### Element Detail

    - #### using

          public abstract Class<? extends JsonSerializer<?>> using

      Serializer class to use for serializing associated value. Depending on what is annotated, value is either an instance of annotated class (used globablly anywhere where class serializer is needed); or only used for serializing property access via a getter method.
      Default:
        org.codehaus.jackson.map.JsonSerializer.None.class

    - #### contentUsing

          public abstract Class<? extends JsonSerializer<?>> contentUsing

      Serializer class to use for serializing contents (elements of a Collection/array, values of Maps) of annotated property. Can only be used on properties (methods, fields, constructors), and not value classes themselves (as they are typically generic)
      Since:
        1.8
      Default:
        org.codehaus.jackson.map.JsonSerializer.None.class

    - #### keyUsing

          public abstract Class<? extends JsonSerializer<?>> keyUsing

      Serializer class to use for serializing Map keys of annotated property. Can only be used on properties (methods, fields, constructors), and not value classes themselves.
      Since:
        1.8
      Default:
        org.codehaus.jackson.map.JsonSerializer.None.class

    - #### as

          public abstract Class<?> as

      Supertype (of declared type, which itself is supertype of runtime type) to use as type when locating serializer to use.

      Bogus type `NoClass` can be used to indicate that declared type is used as is (i.e. this annotation property has no setting); this since annotation properties are not allowed to have null value.

      Note: if `using()` is also used it has precedence (since it directly specifies serializer, whereas this would only be used to locate the serializer) and value of this annotation property is ignored.

      Default:
        org.codehaus.jackson.map.annotate.NoClass.class

    - #### keyAs

          public abstract Class<?> keyAs

      Concrete type to serialize keys of `Map` as, instead of type otherwise declared. Must be a supertype of declared type; otherwise an exception may be thrown by serializer.
      Default:
        org.codehaus.jackson.map.annotate.NoClass.class

    - #### contentAs

          public abstract Class<?> contentAs

      Concrete type to serialize content value (elements of a Collection/array, values of Maps) as, instead of type otherwise declared. Must be a supertype of declared type; otherwise an exception may be thrown by serializer.
      Default:
        org.codehaus.jackson.map.annotate.NoClass.class

    - #### typing

          public abstract JsonSerialize.Typing typing

      Whether type detection used is dynamic or static: that is, whether actual runtime type is used (dynamic), or just the declared type (static).
      Since:
        1.2
      Default:
        org.codehaus.jackson.map.annotate.JsonSerialize.Typing.DYNAMIC

    - #### include

          public abstract JsonSerialize.Inclusion include

      Which properties of annotated Bean are to be included in serialization (has no effect on other types like enums, primitives or collections). Choices are "all", "properties that have value other than null" and "properties that have non-default value" (i.e. default value being property setting for a Bean constructed with default no-arg constructor, often null).
      Default:
        org.codehaus.jackson.map.annotate.JsonSerialize.Inclusion.ALWAYS
