/**
 * @class Ext.data.Types
 * 
This is s static class containing the system-supplied data types which may be given to a {@link Ext.data.Field Field}.

 * 
The properties in this class are used as type indicators in the {@link Ext.data.Field Field} class, so to
 * test whether a Field is of a certain type, compare the {@link Ext.data.Field#type type} property against properties
 * of this class.
 * 
Developers may add their own application-specific data types to this class. Definition names must be UPPERCASE.
 * each type definition must contain three properties:
 * 

 * 
convert : Function
A function to convert raw data values from a data block into the data
 * to be stored in the Field. The function is passed the collowing parameters:
 * 

 * 
v : Mixed
The data value as read by the Reader, if undefined will use
 * the configured {@link Ext.data.Field#defaultValue defaultValue}.
 * 
rec : Mixed
The data object containing the row as read by the Reader.
 * Depending on the Reader type, this could be an Array ({@link Ext.data.ArrayReader ArrayReader}), an object
 * ({@link Ext.data.JsonReader JsonReader}), or an XML element ({@link Ext.data.XMLReader XMLReader}).
 * 
 * 
sortType : Function 
A function to convert the stored data into comparable form, as defined by {@link Ext.data.SortTypes}.
 * 
type : String 
A textual data type name.
 * 
 * 
For example, to create a VELatLong field (See the Microsoft Bing Mapping API) containing the latitude/longitude value of a datapoint on a map from a JsonReader data block
 * which contained the properties lat and long, you would define a new data type like this:
 *

// Add a new Field data type which stores a VELatLong object in the Record.
Ext.data.Types.VELATLONG = {
    convert: function(v, data) {
        return new VELatLong(data.lat, data.long);
    },
    sortType: function(v) {
        return v.Latitude;  // When sorting, order by latitude
    },
    type: 'VELatLong'
};

 * 
Then, when declaring a Record, use 

var types = Ext.data.Types; // allow shorthand type access
UnitRecord = Ext.data.Record.create([
    { name: 'unitName', mapping: 'UnitName' },
    { name: 'curSpeed', mapping: 'CurSpeed', type: types.INT },
    { name: 'latitude', mapping: 'lat', type: types.FLOAT },
    { name: 'latitude', mapping: 'lat', type: types.FLOAT },
    { name: 'position', type: types.VELATLONG }
]);

 * @singleton
