* Converts to and from JSON format.

1178 |
*
|
|
|
1179 |
* JSON (JavaScript Object Notation) is a lightweight data-interchange
|
|
|
1180 |
* format. It is easy for humans to read and write. It is easy for machines
|
|
|
1181 |
* to parse and generate. It is based on a subset of the JavaScript
|
|
|
1182 |
* Programming Language, Standard ECMA-262 3rd Edition - December 1999.
|
|
|
1183 |
* This feature can also be found in Python. JSON is a text format that is
|
|
|
1184 |
* completely language independent but uses conventions that are familiar
|
|
|
1185 |
* to programmers of the C-family of languages, including C, C++, C#, Java,
|
|
|
1186 |
* JavaScript, Perl, TCL, and many others. These properties make JSON an
|
|
|
1187 |
* ideal data-interchange language.
|
|
|
1188 |
*
|
|
|
1189 |
* This package provides a simple encoder and decoder for JSON notation. It
|
|
|
1190 |
* is intended for use with client-side Javascript applications that make
|
|
|
1191 |
* use of HTTPRequest to perform server communication functions - data can
|
|
|
1192 |
* be encoded into JSON notation for use in a client-side javascript, or
|
|
|
1193 |
* decoded from incoming Javascript requests. JSON format is native to
|
|
|
1194 |
* Javascript, and can be directly eval()'ed with no further parsing
|
|
|
1195 |
* overhead
|
|
|
1196 |
*
|
|
|
1197 |
* All strings should be in ASCII or UTF-8 format!
