[ AMD Module Require | Legacy Module Require ]
require(["esri/tasks/locationproviders/LocationProviderBase"], function(LocationProviderBase) { /* code goes here */ });
Description
(Added at v3.12)
(Currently in beta)
The base class for all LocationProviders. This class has no constructor. A provider takes a set of records or features that do not have a geometry associated with it and locates or generates a geometry based on an attribute field that contains some location information such as Street, City or Zip code.Samples
