+/**
+ * @class Ext.Direct
+ * @extends Ext.util.Observable
+ * <p><b><u>Overview</u></b></p>
+ *
+ * <p>Ext.Direct aims to streamline communication between the client and server
+ * by providing a single interface that reduces the amount of common code
+ * typically required to validate data and handle returned data packets
+ * (reading data, error conditions, etc).</p>
+ *
+ * <p>The Ext.direct namespace includes several classes for a closer integration
+ * with the server-side. The Ext.data namespace also includes classes for working
+ * with Ext.data.Stores which are backed by data from an Ext.Direct method.</p>
+ *
+ * <p><b><u>Specification</u></b></p>
+ *
+ * <p>For additional information consult the
+ * <a href="http://extjs.com/products/extjs/direct.php">Ext.Direct Specification</a>.</p>
+ *
+ * <p><b><u>Providers</u></b></p>
+ *
+ * <p>Ext.Direct uses a provider architecture, where one or more providers are
+ * used to transport data to and from the server. There are several providers
+ * that exist in the core at the moment:</p><div class="mdetail-params"><ul>
+ *
+ * <li>{@link Ext.direct.JsonProvider JsonProvider} for simple JSON operations</li>
+ * <li>{@link Ext.direct.PollingProvider PollingProvider} for repeated requests</li>
+ * <li>{@link Ext.direct.RemotingProvider RemotingProvider} exposes server side
+ * on the client.</li>
+ * </ul></div>
+ *
+ * <p>A provider does not need to be invoked directly, providers are added via
+ * {@link Ext.Direct}.{@link Ext.Direct#add add}.</p>
+ *
+ * <p><b><u>Router</u></b></p>
+ *
+ * <p>Ext.Direct utilizes a "router" on the server to direct requests from the client
+ * to the appropriate server-side method. Because the Ext.Direct API is completely
+ * platform-agnostic, you could completely swap out a Java based server solution
+ * and replace it with one that uses C# without changing the client side JavaScript
+ * at all.</p>
+ *
+ * <p><b><u>Server side events</u></b></p>
+ *
+ * <p>Custom events from the server may be handled by the client by adding
+ * listeners, for example:</p>
+ * <pre><code>
+{"type":"event","name":"message","data":"Successfully polled at: 11:19:30 am"}
+
+// add a handler for a 'message' event sent by the server
+Ext.Direct.on('message', function(e){
+ out.append(String.format('<p><i>{0}</i></p>', e.data));
+ out.el.scrollTo('t', 100000, true);
+});
+ * </code></pre>
+ * @singleton

+ * connection where the client can initiate a procedure on the server).</p>
+ *
+ * <p>This allows for code to be organized in a fashion that is maintainable,
+ * while providing a clear path between client and server, something that is
+ * not always apparent when using URLs.</p>
+ *
+ * <p>To accomplish this the server-side needs to describe what classes and methods
+ * are available on the client-side. This configuration will typically be
+ * outputted by the server-side Ext.Direct stack when the API description is built.</p>

+ * <pre><code>
+"actions":{ // each property within the 'actions' object represents a server side Class
+ "TestAction":[ // array of methods within each server side Class to be
+ { // stubbed out on client
+ "name":"doEcho",
+ "len":1
+ },{
+ "name":"multiply",// name of method
+ "len":2 // The number of parameters that will be used to create an

+ },{
+ "name":"doForm",
+ "formHandler":true, // direct the client to use specialized form handling method
+ "len":1
+ }]
+}
+ * </code></pre>
+ * <p>Note that a Store is not required, a server method can be called at any time.
+ * In the following example a <b>client side</b> handler is used to call the
+ * server side method "multiply" in the server-side "TestAction" Class:</p>
+ * <pre><code>
+TestAction.multiply(
+ 2, 4, // pass two arguments to server, so specify len=2
+ // callback function after the server is called
+ // result: the result returned by the server
+ // e: Ext.Direct.RemotingEvent object

+ var t = e.getTransaction();
+ var action = t.action; // server side Class called
+ var method = t.method; // server side method called
+ if(e.status){
+ var answer = Ext.encode(result); // 8
+
+ }else{
+ var msg = e.message; // failure message
+ }
+ }
+);
+ * </code></pre>
+ * In the example above, the server side "multiply" function will be passed two
+ * arguments (2 and 4). The "multiply" method should return the value 8 which will be
+ * available as the <tt>result</tt> in the example above.
