Ext.AbstractManager
Ext.ComponentManager

Provides a registry of all Components (instances of Ext.Component or any subclass +thereof) on a page so that they can be easily accessed by component +id (see get, or the convenience method Ext.getCmp).

+ + +

This object also provides a registry of available Component classes +indexed by a mnemonic code known as the Component's xtype. +The xtype provides a way to avoid instantiating child Components +when creating a full, nested config object for a complete Ext page.

+ + +

A child Component may be specified simply as a config object +as long as the correct xtype is specified so that if and when the Component +needs rendering, the correct type can be looked up for lazy instantiation.

+ + +

For a list of all available xtypes, see Ext.Component.
