22 * A service which stores a subset of scored networks from the active network scorer.
23 *
24 * <p>To be implemented by network subsystems (e.g. Wi-Fi). NetworkScoreService will propagate
25 * scores down to each subsystem depending on the network type. Implementations may register for
26 * a given network type by calling NetworkScoreManager.registerNetworkSubsystem.
27 *
28 * <p>A proper implementation should throw SecurityException whenever the caller is not privileged.
29 * It may request scores by calling NetworkScoreManager#requestScores(NetworkKey[]); a call to
30 * updateScores may follow but may not depending on the active scorer's implementation, and in
31 * general this method may be called at any time.
32 *
33 * <p>Implementations should also override dump() so that "adb shell dumpsys network_score" includes
34 * the current scores for each network for debugging purposes.
