+ '' @SDESCRIPTION: generates a representation of a name value pair in JSON grammer\r
+ '' @DESCRIPTION: It generates a name value pair which is represented as <em>{"name": value}</em> in JSON.\r
+ '' the generation is fully recursive. Thus the value can also be a complex datatype (array in dictionary, etc.) e.g.\r
+ '' <code>\r
+ '' <%\r
+ '' set j = new JSON\r
+ '' j.toJSON "n", array(RS, dict, false), false\r
+ '' j.toJSON "n", array(array(), 2, true), false\r
+ '' % >\r
+ '' </code>\r
+ '' @PARAM: name [string]: name of the value (accessible with javascript afterwards). leave empty to get just the value\r
+ '' @PARAM: val [variant], [int], [float], [array], [object], [dictionary]: value which needs\r
+ '' to be generated. Conversation of the data types is as follows:<br>\r
+ '' - <strong>ASP datatype -> JavaScript datatype</strong>\r
+ '' - NOTHING, NULL -> null\r
+ '' - INT, DOUBLE -> number\r
+ '' - STRING -> string\r
+ '' - BOOLEAN -> bool\r
+ '' - ARRAY -> array\r
+ '' - DICTIONARY -> Represents it as name value pairs. Each key is accessible as property afterwards. json will look like <code>"name": {"key1": "some value", "key2": "other value"}</code>\r
+ '' - <em>multidimensional array</em> -> Generates a 1-dimensional array (flat) with all values of the multidimensional array\r
+ '' - <em>request</em> object -> every property and collection (cookies, form, querystring, etc) of the asp request object is exposed as an item of a dictionary. Property names are <strong>lowercase</strong>. e.g. <em>servervariables</em>.\r
+ '' - OBJECT -> name of the type (if unknown type) or all its properties (if class implements <em>reflect()</em> method)\r
+ '' Implement a <strong>reflect()</strong> function if you want your custom classes to be recognized. The function must return\r
+ '' a dictionary where the key holds the property name and the value its value. Example of a reflect function within a User class which has firstname and lastname properties\r
+ '' <code>\r
+ '' <%\r
+ '' function reflect()\r
+ '' . set reflect = server.createObject("scripting.dictionary")\r
+ '' . reflect.add "firstname", firstname\r
+ '' . reflect.add "lastname", lastname\r
+ '' end function\r
+ '' % >\r
+ '' </code>\r
+ '' Example of how to generate a JSON representation of the asp request object and access the <em>HTTP_HOST</em> server variable in JavaScript:\r
+ '' <code>\r
+ '' <script>alert(<%= (new JSON)(empty, request, false) % >.servervariables.HTTP_HOST);</script>\r
+ '' </code>\r
+ '' @PARAM: nested [bool]: indicates if the name value pair is already nested within another? if yes then the <em>{}</em> are left out.\r
+ '' @RETURN: [string] returns a JSON representation of the given name value pair\r
