+ * @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>
