</span> * @class Ext.ComponentManager
 * &lt;p&gt;Provides a registry of all Components (instances of {@link Ext.Component} or any subclass
 * thereof) on a page so that they can be easily accessed by {@link Ext.Component component}
 * {@link Ext.Component#id id} (see {@link #get}, or the convenience method {@link Ext#getCmp Ext.getCmp}).&lt;/p&gt;
 * &lt;p&gt;This object also provides a registry of available Component &lt;i&gt;classes&lt;/i&gt;
 * indexed by a mnemonic code known as the Component's {@link Ext.Component#xtype xtype}.
 * The &lt;code&gt;xtype&lt;/code&gt; provides a way to avoid instantiating child Components
 * when creating a full, nested config object for a complete Ext page.&lt;/p&gt;
 * &lt;p&gt;A child Component may be specified simply as a &lt;i&gt;config object&lt;/i&gt;
 * as long as the correct &lt;code&gt;{@link Ext.Component#xtype xtype}&lt;/code&gt; is specified so that if and when the Component
 * needs rendering, the correct type can be looked up for lazy instantiation.&lt;/p&gt;
 * &lt;p&gt;For a list of all available &lt;code&gt;{@link Ext.Component#xtype xtypes}&lt;/code&gt;, see {@link Ext.Component}.&lt;/p&gt;
