-// A wifi data provider provides wifi data from the device that is used by a |
-// NetworkLocationProvider to obtain a position fix. We use a singleton |
-// instance of the wifi data provider manager, which is used by multiple |
-// NetworkLocationProvider objects. |
-// |
-// This file provides WifiDataProviderManager, which provides static methods to |
-// access the singleton instance. The singleton instance uses a private |
-// implementation of WifiDataProvider to abstract across platforms and also to |
-// allow mock providers to be used for testing. |
