new CoordinatesLocationProvider(options)

Creates a new instance of the CoordinatesLocationProvider object.
Parameters:
<Object> options Required Define the properties to use when creating the class. See options descriptions for further information.
options properties:
<String> xField Required The attribute field in the graphic object that contains the longitude (X) values.
<String> yField Required The attribute field in the graphic object that has the latitude (Y) values.
Sample:
require([
   "esri/tasks/locationproviders/CoordinatesLocationProvider",..
], function(CoordinatesLocationProvider,...) {
   var locationProvider: new CoordinatesLocationProvider({
       xField: 'X',

   });
   ...
   locationProvider.locate(graphicsArray).then(function(results) {
     ...
   });
});
Property Details

<String> geometryType

The geometry type of the returned features.

Method Details

locate(features, options?)

Assigns geometries to the array of Graphic objects.
Return type: Deferred
Parameters:
<Graphic[]> features Required An array of Graphic objects.
<Object> options Optional Optional parameters. See the Object Specifications table below for the structure of the options object.
Object Specifications:
<options>
<SpatialReference> outSpatialReference Required Spatial reference of the output geometry. Defaults to 4326 when not provided.
<Boolean> useExistingGeometries Required A property to notify whether geometry should be located for Graphic object that already has a geometry. The default value is false.
