 8 * @class Ext.data.ArrayStore
 9 * @extends Ext.data.Store
10 * <p>Formerly known as "SimpleStore".</p>
11 * <p>Small helper class to make creating {@link Ext.data.Store}s from Array data easier.
12 * An ArrayStore will be automatically configured with a {@link Ext.data.ArrayReader}.</p>
13 * <p>A store configuration would be something like:<pre><code>
14var store = new Ext.data.ArrayStore({
15    // store configs
16    autoDestroy: true,
17    storeId: 'myStore',
18    // reader configs
19    idIndex: 0,  
20    fields: [
21       'company',
22       {name: 'price', type: 'float'},
23       {name: 'change', type: 'float'},
24       {name: 'pctChange', type: 'float'},
25       {name: 'lastChange', type: 'date', dateFormat: 'n/j h:ia'}
26    ]
27});
28 * </code></pre></p>
29 * <p>This store is configured to consume a returned object of the form:<pre><code>
30var myData = [
31    ['3m Co',71.72,0.02,0.03,'9/1 12:00am'],
32    ['Alcoa Inc',29.01,0.42,1.47,'9/1 12:00am'],
33    ['Boeing Co.',75.43,0.53,0.71,'9/1 12:00am'],
34    ['Hewlett-Packard Co.',36.53,-0.03,-0.08,'9/1 12:00am'],
35    ['Wal-Mart Stores, Inc.',45.45,0.73,1.63,'9/1 12:00am']
36];
37 * </code></pre>
38 * An object literal of this form could also be used as the {@link #data} config option.</p>
39 * <p><b>*Note:</b> Although not listed here, this class accepts all of the configuration options of 
40 * <b>{@link Ext.data.ArrayReader ArrayReader}</b>.</p>
41 * @constructor
42 * @param {Object} config
43 * @xtype arraystore
