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
: FunctionsortType
: Function type
: String 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 }
]
});
This data type means that no conversion is applied to the raw data before it is placed into a Record.
This data type means that no conversion is applied to the raw data before it is placed into a Record.
This data type means that the raw data is converted into a boolean before it is placed into
a Record. The string "true" and the number 1 are converted to boolean true
.
The synonym BOOLEAN
is equivalent.
This data type means that the raw data is converted into a boolean before it is placed into
a Record. The string "true" and the number 1 are converted to boolean true
.
The synonym BOOL
is equivalent.
This data type means that the raw data is converted into a Date before it is placed into a Record. The date format is specified in the constructor of the Ext.data.Field to which this type is being applied.
This data type means that the raw data is converted into a number before it is placed into a Record.
The synonym NUMBER
is equivalent.
This data type means that the raw data is converted into an integer before it is placed into a Record.
The synonym INTEGER
is equivalent.
This data type means that the raw data is converted into an integer before it is placed into a Record.
The synonym INT
is equivalent.
This data type means that the raw data is converted into a number before it is placed into a Record.
The synonym FLOAT
is equivalent.
This data type means that the raw data is converted into a String before it is placed into a Record.
This data type means that the raw data is converted into a String before it is placed into a Record.
