Javascript eXpressive Framework

<script src="https://google-code-prettify.googlecode.com/svn/loader/run_prettify.js"></script>

The goal of this framework is to provide an expressive wrapper around certain tasks so as to make Javascript code a bit readable. The approach leverages well known design patterns and guarantees compatibility with existing frameworks like JQuery, Mootools, Dojo, gRaphael, Jqplot ...

Additionally we organized the the interfaces into files that implement scopes. Making Jx truely expressive within a context defined by a scope:

dom.js	rpc.js	utils.js	math.js	ml.js	charts.js
Handles DOM objects	Handles remote calls (AJAX)	Reusable collection handlers & design patterns	Essential math (sets) & statistical functions	Machine learning approaches like mapreduce	Implements an interface to jqplot

The implementation is designed to provide to an expressive, workable and easy to use interface when working with Javascript We use standard design patterns and have documented the code extensively for anyone to contribute

We have a Nodejs port. Due to the areas of application of nodejs, we have primarily enabled:

* math.js 	for mathematics & statistic functions
* ml.js: 	for machine learning
* utils.js	for collection handling and design pattherns

#dom.js

This file handles DOM object operations with a simple interface. The namespace it belongs to is identified/prefixed by jx.dom This will mostly refer to DOM objects by their identifiers

Preconditions: The DOM object identifier must always be set

jx.dom.show

Makes a DOM Object visible
applies: ALL

jx.dom.hide

Makes a DOM Object invisible
applies: ALL

jx.dom.set.value

Sets the value of an object provided its identifier.
applies: SELECT, DIV, SPAN, INPUT, TEXTAREA

jx.dom.set.attribute

This function will set an attribute on a DOM object, the attributes can be standard or custom
applies: ALL

jx.dom.set.css

This function will set a css to an existing className object of a DOM object
applies: ALL

jx.dom.set.style

This function will set an attribute on the style object. 
It is equivalent to adding an inline css entry to a DOM object
applies: ALL

jx.dom.set.focus

This function will allow focus on a DOM object that permits it
applies: INPUT

jx.dom.get.instance

This function will return an existing DOM object or create a new one:
	- If a DOM identifier is entered it will return the DOM Object
	- If a keyword is provided it will create an instance of the DOM Object
applies: ALL

jx.dom.get.value

Returns the value from a DOM Object provided an identifier
applies: SELECT,DIV, SPAN,INPUT, TEXTAREA

jx.dom.get.children

Returns the list of children nodes under a specified DOM object
applies: ALL

jx.dom.append

Appends a DOM object to an existing one that is specified an identifier
applies: ALL

jx.dom.remove

Removes a DOM object from it's parent, and returns the object.
applies: ALL

#rpc.js

This file implements a expressive AJAX handler that is W3C Compliant: This makes it incompatible with versions of Internet Explorer that are not W3C compliant.

HttpClient.instance

This class creates an AJAX handler to the calling code.

example:
var httpclient = HttpClient.instance()

The object has the following interface once instanciated. We assume the object created is called httpclient

httpclient.setData(object)

This function will set data that will be processed with a request (POST|PUT) The object set can be of any type

httpclient.setHeader(key,value)

This function is designed to set the headers that will be processed with a request (GET|POST|PUT)

parameters:
	key	key of the header
	value	value associated with the key
	
NOTE: will override existing keys

httpclient.<get|post|put>(url,callback)

This function will process a GET, POST, PUT request against a given endpoint

url:	Endpoint (or API)
callback: call back that handles the the enpoints response
