-/**
- * @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

- * <p>This allows for code to be organized in a fashion that is maintainable,
