|
|
|
- * 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!
