| /** | |
| * 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! | |
