## Enum JsonFormat.Shape

- java.lang.Object
- - java.lang.Enum<JsonFormat.Shape>
  - - com.fasterxml.jackson.annotation.JsonFormat.Shape

- All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<JsonFormat.Shape>
  Enclosing class:
    JsonFormat

      public static enum JsonFormat.Shape
      extends java.lang.Enum<JsonFormat.Shape>

  Value enumeration used for indicating preferred Shape; translates loosely to JSON types, with some extra values to indicate less precise choices (i.e. allowing one of multiple actual shapes)

- - ### Enum Constant Summary

    Enum Constants
    Enum Constant and Description
    `ANY` Marker enum value that indicates "whatever" choice, meaning that annotation does NOT specify shape to use.
    `ARRAY` Value that indicates that (JSON) Array type should be used.
    `BOOLEAN` Value that indicates that (JSON) boolean type (true, false) should be used.
    `NATURAL` Marker enum value that indicates the "default" choice for given datatype; for example, JSON String for `String`, or JSON Number for Java numbers.
    `NUMBER` Value that indicates that a numeric (JSON) type should be used (but does not specify whether integer or floating-point representation should be used)
    `NUMBER_FLOAT` Value that indicates that floating-point numeric type should be used
    `NUMBER_INT` Value that indicates that integer number type should be used (and not `NUMBER_FLOAT`).
    `OBJECT` Value that indicates that (JSON) Object type should be used.
    `SCALAR` Value that indicates shape should not be structural (that is, not `ARRAY` or `OBJECT`, but can be any other shape.
    `STRING` Value that indicates that (JSON) String type should be used.

  - ### Method Summary

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `boolean` | `isNumeric()`
    `boolean` | `isStructured()`
    `static JsonFormat.Shape` | `valueOf(java.lang.String name)` Returns the enum constant of this type with the specified name.
    `static JsonFormat.Shape[]` | `values()` Returns an array containing the constants of this enum type, in the order they are declared.

    - #### ANY

          public static final JsonFormat.Shape ANY

      Marker enum value that indicates "whatever" choice, meaning that annotation does NOT specify shape to use. Note that this is different from `NATURAL`, which specifically instructs use of the "natural" shape for datatype.

    - #### NATURAL

          public static final JsonFormat.Shape NATURAL

      Marker enum value that indicates the "default" choice for given datatype; for example, JSON String for `String`, or JSON Number for Java numbers. Note that this is different from `ANY` in that this is actual explicit choice that overrides possible default settings.

    - #### SCALAR

          public static final JsonFormat.Shape SCALAR

      Value that indicates shape should not be structural (that is, not `ARRAY` or `OBJECT`, but can be any other shape.

    - #### ARRAY

          public static final JsonFormat.Shape ARRAY

      Value that indicates that (JSON) Array type should be used.

    - #### OBJECT

          public static final JsonFormat.Shape OBJECT

      Value that indicates that (JSON) Object type should be used.

    - #### NUMBER

          public static final JsonFormat.Shape NUMBER

      Value that indicates that a numeric (JSON) type should be used (but does not specify whether integer or floating-point representation should be used)

    - #### NUMBER_FLOAT

          public static final JsonFormat.Shape NUMBER_FLOAT

      Value that indicates that floating-point numeric type should be used

    - #### NUMBER_INT

          public static final JsonFormat.Shape NUMBER_INT

      Value that indicates that integer number type should be used (and not `NUMBER_FLOAT`).

    - #### STRING

          public static final JsonFormat.Shape STRING

      Value that indicates that (JSON) String type should be used.

    - #### BOOLEAN

          public static final JsonFormat.Shape BOOLEAN

      Value that indicates that (JSON) boolean type (true, false) should be used.

  - ### Method Detail

    - #### values

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

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

    - #### valueOf

          public static JsonFormat.Shape 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

    - #### isNumeric

          public boolean isNumeric()

    - #### isStructured

          public boolean isStructured()
