20 * This class defines Message.what base addresses for various protocols that are recognized
21 * to be unique by any {@link com.android.internal.util.Statemachine} implementation. This
22 * allows for interaction between different StateMachine implementations without a conflict
23 * of message codes.
24 *
25 * As an example, all messages in {@link android.net.wifi.WifiStateMachine} will have message
26 * codes with Message.what starting at Protocol.WIFI + 1 and less than or equal to Protocol.WIFI +
27 * Protocol.MAX_MESSAGE
28 *
29 * NOTE: After a value is created and source released a value shouldn't be changed to
30 * maintain backwards compatibility.
