/**

-
* Converts to and from JSON format.
|
| 6 |
-
*
|
| 7 |
-
* JSON (JavaScript Object Notation) is a lightweight data-interchange
|
| 8 |
-
* format. It is easy for humans to read and write. It is easy for machines
|
| 9 |
-
* to parse and generate. It is based on a subset of the JavaScript
|
| 10 |
-
* Programming Language, Standard ECMA-262 3rd Edition - December 1999.
|
| 11 |
-
* This feature can also be found in Python. JSON is a text format that is
|
| 12 |
-
* completely language independent but uses conventions that are familiar
|
| 13 |
-
* to programmers of the C-family of languages, including C, C++, C#, Java,
|
| 14 |
-
* JavaScript, Perl, TCL, and many others. These properties make JSON an
|
| 15 |
-
* ideal data-interchange language.
|
| 16 |
-
*
|
| 17 |
-
* This package provides a simple encoder and decoder for JSON notation. It
|
| 18 |
-
* is intended for use with client-side Javascript applications that make
|
| 19 |
-
* use of HTTPRequest to perform server communication functions - data can
|
| 20 |
-
* be encoded into JSON notation for use in a client-side javascript, or
|
| 21 |
-
* decoded from incoming Javascript requests. JSON format is native to
|
| 22 |
-
* Javascript, and can be directly eval()'ed with no further parsing
|
| 23 |
-
* overhead
|
| 24 |
-
*
|
| 25 |
-
* All strings should be in ASCII or UTF-8 format!

/**

* Converts to and from JSON format.
|
| 6 |
+
*
|
| 7 |
+
* JSON (JavaScript Object Notation) is a lightweight data-interchange
|
| 8 |
+
* format. It is easy for humans to read and write. It is easy for machines
|
| 9 |
+
* to parse and generate. It is based on a subset of the JavaScript
|
| 10 |
+
* Programming Language, Standard ECMA-262 3rd Edition - December 1999.
|
| 11 |
+
* This feature can also be found in Python. JSON is a text format that is
|
| 12 |
+
* completely language independent but uses conventions that are familiar
|
| 13 |
+
* to programmers of the C-family of languages, including C, C++, C#, Java,
|
| 14 |
+
* JavaScript, Perl, TCL, and many others. These properties make JSON an
|
| 15 |
+
* ideal data-interchange language.
|
| 16 |
+
*
|
| 17 |
+
* This package provides a simple encoder and decoder for JSON notation. It
|
| 18 |
+
* is intended for use with client-side Javascript applications that make
|
| 19 |
+
* use of HTTPRequest to perform server communication functions - data can
|
| 20 |
+
* be encoded into JSON notation for use in a client-side javascript, or
|
| 21 |
+
* decoded from incoming Javascript requests. JSON format is native to
|
| 22 |
+
* Javascript, and can be directly eval()'ed with no further parsing
|
| 23 |
+
* overhead
|
| 24 |
+
*
|
| 25 |
+
* All strings should be in ASCII or UTF-8 format!
