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 }
    ]
});
