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.
      • -
    • -
  • 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 Model, use -

var types = Ext.data.Types; // allow shorthand type access
-Ext.define('Unit',
-    extend: 'Ext.data.Model', 
-    fields: [
-        { 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 }
-    ]
-});
