Class JSON

cassia.util.JSON

Direct Known Subclasses:

JSON

public class JSON

A JSON parser written in X10.

Restrictions:

• No type recognition for literals (stored as string)
• No escape sequence handling

Use JSON.parse() to obtain a JSON object from a string or file.

See JSON.Value to know how to access to the JSON data.

Syntax:

    json := object
    name := ( string | literal )
    value := ( object | array | string | literal )
    object := "{" [ name ":" value [ "," name ":" value ]* ] "}"
    array := "[" [ value [ "," value ]* ] "]"
    string := QUOTE [ CHARACTER ]* QUOTE
    literal := ( LETTERS | DIGITS | "_" | "." | "+" | "-" )+
