Enum Json.ValueType

java.lang.Object

java.lang.Enum<Json.ValueType>

de.caff.io.json.Json.ValueType

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Json.ValueType>

Enclosing class:

Json

public static enum Json.ValueType
extends java.lang.Enum<Json.ValueType>

The different value types in JSON.

Values appear as values of key-value pairs in JSON objects, and as elements in JSON arrays.

The uppermost item in a JSON file is always a value, mostly an Object.

Boolean A JSON boolean value, either true or false.
Null A JSON null value.
Number A JSON number.
Object A JSON object, i.e. a container with key-value pairs.
String A JSON string, i.e. a piece of text.

Enum Constant Detail

Object

public static final Json.ValueType Object

A JSON object, i.e. a container with key-value pairs.

Array

public static final Json.ValueType Array

A JSON array, i.e. a container with a bunch of value elements.

String

public static final Json.ValueType String

A JSON string, i.e. a piece of text.

Number

public static final Json.ValueType Number

A JSON number. As JSON derives from JavaScript, numbers are always 8-byte IEEE 754 floating-point numbers, i.e. a double in the java sense. This creates a bunch of problems, e.g. it's impossible to represent all long integers.

Boolean

public static final Json.ValueType Boolean

A JSON boolean value, either true or false.

Null

public static final Json.ValueType Null

A JSON null value.

Method Detail

values

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

Returns:

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

valueOf

public static Json.ValueType 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

getDisplayName

@NotNull
public java.lang.String getDisplayName()

Get the display name of this enum.

Returns:

display name
