+ * Instances of this class encapsulate both record <em>definition</em> information, and record
+ * <em>value</em> information for use in {@link Roo.data.Store} objects, or any code which needs
+ * to access Records cached in an {@link Roo.data.Store} object.<br>
+ * <p>
+ * Constructors for this class are generated by passing an Array of field definition objects to {@link #create}.
+ * Instances are usually only created by {@link Roo.data.Reader} implementations when processing unformatted data
+ * objects.<br>
+ * <p>
+ * Record objects generated by this constructor inherit all the methods of Roo.data.Record listed below.
+ * @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: <ul>
+ * <li><b>name</b> : String<p style="margin-left:1em">The name by which the field is referenced within the Record. This is referenced by,
+ * for example the <em>dataIndex</em> property in column definition objects passed to {@link Roo.grid.ColumnModel}</p></li>
+ * <li><b>mapping</b> : String<p style="margin-left:1em">(Optional) A path specification for use by the {@link Roo.data.Reader} implementation
+ * that is creating the Record to access the data value from the data object. If an {@link Roo.data.JsonReader}
+ * is being used, then this is a string containing the javascript expression to reference the data relative to
+ * the record item's root. If an {@link Roo.data.XmlReader} is being used, this is an {@link Roo.DomQuery} path
+ * to the data item relative to the record element. If the mapping expression is the same as the field name,
+ * this may be omitted.</p></li>
+ * <li><b>type</b> : String<p style="margin-left:1em">(Optional) The data type for conversion to displayable value. Possible values are
+ * <ul><li>auto (Default, implies no conversion)</li>
+ * <li>string</li>
+ * <li>int</li>
+ * <li>float</li>
+ * <li>boolean</li>
+ * <li>date</li></ul></p></li>
+ * <li><b>sortType</b> : Mixed<p style="margin-left:1em">(Optional) A member of {@link Roo.data.SortTypes}.</p></li>
+ * <li><b>sortDir</b> : String<p style="margin-left:1em">(Optional) Initial direction to sort. "ASC" or "DESC"</p></li>
+ * <li><b>convert</b> : Function<p style="margin-left:1em">(Optional) A function which converts the value provided
+ * by the Reader into an object that will be stored in the Record. It is passed the
+ * following parameters:<ul>
+ * <li><b>v</b> : Mixed<p style="margin-left:1em">The data value as read by the Reader.</p></li>
+ * </ul></p></li>
+ * <li><b>dateFormat</b> : String<p style="margin-left:1em">(Optional) A format String for the Date.parseDate function.</p></li>
+ * </ul>
