/**
|
||||
* Converts to and from JSON format.
|
||||
*
|
||||
* JSON (JavaScript Object Notation) is a lightweight data-interchange
|
||||
* format. It is easy for humans to read and write. It is easy for machines
|
||||
* to parse and generate. It is based on a subset of the JavaScript
|
||||
* Programming Language, Standard ECMA-262 3rd Edition - December 1999.
|
||||
* This feature can also be found in Python. JSON is a text format that is
|
||||
* completely language independent but uses conventions that are familiar
|
||||
* to programmers of the C-family of languages, including C, C++, C#, Java,
|
||||
* JavaScript, Perl, TCL, and many others. These properties make JSON an
|
||||
* ideal data-interchange language.
|
||||
*
|
||||
* This package provides a simple encoder and decoder for JSON notation. It
|
||||
* is intended for use with client-side Javascript applications that make
|
||||
* use of HTTPRequest to perform server communication functions - data can
|
||||
* be encoded into JSON notation for use in a client-side javascript, or
|
||||
* decoded from incoming Javascript requests. JSON format is native to
|
||||
* Javascript, and can be directly eval()'ed with no further parsing
|
||||
* overhead
|
||||
*
|
||||
* All strings should be in ASCII or UTF-8 format!
