Enum Constant Detail

BEGIN_ARRAY

public static final JsonToken BEGIN_ARRAY

The opening of a JSON array. Written using JsonWriter.beginArray() and read using JsonReader.beginArray().

END_ARRAY

public static final JsonToken END_ARRAY

The closing of a JSON array. Written using JsonWriter.endArray() and read using JsonReader.endArray().

BEGIN_OBJECT

public static final JsonToken BEGIN_OBJECT

The opening of a JSON object. Written using JsonWriter.beginObject() and read using JsonReader.beginObject().

END_OBJECT

public static final JsonToken END_OBJECT

The closing of a JSON object. Written using JsonWriter.endObject() and read using JsonReader.endObject().

NAME

public static final JsonToken NAME

A JSON property name. Within objects, tokens alternate between names and their values. Written using JsonWriter.name(java.lang.String) and read using JsonReader.nextName()

STRING

public static final JsonToken STRING

A JSON string.

NUMBER

public static final JsonToken NUMBER

A JSON number represented in this API by a Java double, long, or int.

BOOLEAN

public static final JsonToken BOOLEAN

A JSON true or false.

NULL

public static final JsonToken NULL

A JSON null.

END_DOCUMENT

public static final JsonToken END_DOCUMENT

The end of the JSON stream. This sentinel value is returned by JsonReader.peek() to signal that the JSON-encoded value has no more tokens.

Method Detail

values

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

Returns:

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

valueOf

public static JsonToken valueOf(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:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
