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.
