# Class Ext.data.Types

Package: | Ext.data
Defined In: | Types.js
Class: | Types
Extends: | Object

This is s static class containing the system-supplied data types which may be given to a Field.

The properties in this class are used as type indicators in the Field class, so to test whether a Field is of a certain type, compare the 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 `defaultValue`.
  - rec : Mixed
    The data object containing the row as read by the Reader. Depending on the Reader type, this could be an Array (ArrayReader), an object (JsonReader), or an XML element (XMLReader).
- `sortType` : Function
  A function to convert the stored data into comparable form, as defined by 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 }
    ]);

This class is a singleton and cannot be created directly.
