| 5 // Defines the Geolocation access token store, and associated factory function. |
| 6 // An access token store is responsible for providing the API to persist |
| 7 // access tokens, one at a time, and to load them back on mass. |
| 8 // The API is a little more complex than one might wish, due to the need for |
| 9 // prefs access to happen asynchronously on the UI thread. |
| 10 // This API is provided as abstract base classes to allow mocking and testing |
| 11 // of clients, without dependency on browser process singleton objects etc. |
