</span></span> * @class Ext.data.ArrayReader
* @extends Ext.data.JsonReader
* <p>Data reader class to create an Array of {@link Ext.data.Record} objects from an Array.
* Each element of that Array represents a row of data fields. The
* fields are pulled into a Record object using as a subscript, the <code>mapping</code> property
* of the field definition if it exists, or the field's ordinal position in the definition.</p>
* <p>Example code:</p>
* <pre><code>
var Employee = Ext.data.Record.create([
{name: 'name', mapping: 1}, // "mapping" only needed if an "id" field is present which
{name: 'occupation', mapping: 2} // precludes using the ordinal position as the index.
]);
var myReader = new Ext.data.ArrayReader({
{@link #idIndex}: 0
}, Employee);
</code></pre>
* <p>This would consume an Array like this:</p>
* <pre><code>
[ [1, 'Bill', 'Gardener'], [2, 'Ben', 'Horticulturalist'] ]
* </code></pre>
* @constructor
* Create a new ArrayReader
* @param {Object} meta Metadata configuration options.
* @param {Array/Object} recordType
* <p>Either an Array of {@link Ext.data.Field Field} definition objects (which
* will be passed to {@link Ext.data.Record#create}, or a {@link Ext.data.Record Record}
* constructor created from {@link Ext.data.Record#create}.</p>
