| /** |
| * This class describes the available routes of a call as a state machine. |
| * Transitions are caused solely by the commands sent as messages. Possible values for msg.what |
| * are defined as event constants in this file. |
| * |
| * The eight states are all instances of the abstract base class, {@link AudioState}. Each state |
| * is a combination of one of the four audio routes (earpiece, wired headset, bluetooth, and |
| * speakerphone) and audio focus status (active or quiescent). |
| * |
| * Messages are processed first by the processMessage method in the base class, AudioState. |
| * Any messages not completely handled by AudioState are further processed by the same method in |
| * the route-specific abstract classes: {@link EarpieceRoute}, {@link HeadsetRoute}, |
| * {@link BluetoothRoute}, and {@link SpeakerRoute}. Finally, messages that are not handled at |
| * this level are then processed by the classes corresponding to the state instances themselves. |
| * |
| * There are several variables carrying additional state. These include: |
| * mAvailableRoutes: A bitmask describing which audio routes are available |
| * mWasOnSpeaker: A boolean indicating whether we should switch to speakerphone after disconnecting |
| * from a wired headset |
| * mIsMuted: a boolean indicating whether the audio is muted |
