- * to access Records cached in an {@link Roo.data.Store} object.&lt;br&gt;
- * &lt;p&gt;
- * Constructors for this class are generated by passing an Array of field definition objects to {@link #create}.

- * @constructor
- * This constructor should not be used to create Record objects. Instead, use the constructor generated by
- * {@link #create}. The parameters are the same.
- * @param {Array} data An associative Array of data values keyed by the field name.
- * @param {Object} id (Optional) The id of the record. This id should be unique, and is used by the
- * {@link Roo.data.Store} object which owns the Record to index its collection of Records. If
- * not specified an integer id is generated.

- * Generate a constructor for a specific record layout.
- * @param {Array} o An Array of field definition objects which specify field names, and optionally,
- * data types, and a mapping for an {@link Roo.data.Reader} to extract the field's value from a data object.
- * Each field definition object may contain the following properties: &lt;ul&gt;
- * &lt;li&gt;&lt;b&gt;name&lt;/b&gt; : String&lt;p style=&quot;margin-left:1em&quot;&gt;The name by which the field is referenced within the Record. This is referenced by,
- * for example the &lt;em&gt;dataIndex&lt;/em&gt; property in column definition objects passed to {@link Roo.grid.ColumnModel}&lt;/p&gt;&lt;/li&gt;

- * &lt;li&gt;&lt;b&gt;convert&lt;/b&gt; : Function&lt;p style=&quot;margin-left:1em&quot;&gt;(Optional) A function which converts the value provided
