            <p>Provides a registry of all Components (specifically subclasses of
17 
<a ext:cls="Ext.Component" href="output/Ext.Component.html">Ext.Component</a>) on a page so that they can be easily accessed by
18 
component id (see <a ext:cls="Ext.getCmp" href="output/Ext.getCmp.html">Ext.getCmp</a>).</p>
19 
<p>This object also provides a registry of available Component <i>classes</i>
20 
indexed by a mnemonic code known as the Component's <a ext:cls="Ext.Component" ext:member="xtype" href="output/Ext.Component.html#xtype">Ext.Component.xtype</a>.
21 
The <tt>xtype</tt> provides a way to avoid instantiating child Components
22 
when creating a full, nested config object for a complete Ext page.</p>
23 
<p>
24 
A child Component may be specified simply as a <i>config object</i>
25 
as long as the correct xtype is specified so that if and when the Component
26 
needs rendering, the correct type can be looked up for lazy instantiation.</p>
27 
<p>For a list of all available xtypes, see <a ext:cls="Ext.Component" href="output/Ext.Component.html">Ext.Component</a>.</p><br><br><i>This class is a singleton and cannot be created directly.</i>        </div>
