| /** |
| * This class is responsible for keeping all knowledge about |
| * Universal Integrated Circuit Card (UICC), also know as SIM's, |
| * in the system. It is also used as API to get appropriate |
| * applications to pass them to phone and service trackers. |
| * |
| * UiccController is created with the call to make() function. |
| * UiccController is a singleton and make() must only be called once |
| * and throws an exception if called multiple times. |
| * |
| * Once created UiccController registers with RIL for "on" and "unsol_sim_status_changed" |
| * notifications. When such notification arrives UiccController will call |
| * getIccCardStatus (GET_SIM_STATUS). Based on the response of GET_SIM_STATUS |
| * request appropriate tree of uicc objects will be created. |
| * |
| * Following is class diagram for uicc classes: |
