This class encodes and decodes JSON strings. Spec. details, see http://www.json.org/ JSON uses Arrays and Objects. These correspond here to the datatypes ArrayList and Hashtable. All numbers are parsed to doubles.

Public Methods

Method	Description
GetLastErrorIndex ( ) : int	On decoding, this function returns the position at which the parse failed (-1 = no error).
GetLastErrorSnippet ( ) : string	If a decoding error occurred, this function returns a piece of the JSON string at which the error took place. To ease debugging.
JsonDecode ( string json ) : object	Parses the string json into a value
JsonEncode ( object json ) : string	Converts a Hashtable / ArrayList object into a JSON string
LastDecodeSuccessful ( ) : bool	On decoding, this function returns the position at which the parse failed (-1 = no error).
