/**
 * A service which stores a subset of scored networks from the active network scorer.

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