# Class Ext.state.Manager

Package: | Ext.state
Defined In: | StateManager.js
Class: | Manager
Extends: | Object

This is the global state manager. By default all components that are "state aware" check this class for state information if you don't pass them a custom state provider. In order for this class to be useful, it must be initialized with a provider when your application initializes. Example usage:

    // in your initialization function
    init : function(){
       Ext.state.Manager.setProvider(new Ext.state.CookieProvider());
       var win = new Window(...);
       win.restoreState();
    }

This class is a singleton and cannot be created directly.
