// The ARC++ camera HAL v3 Mojo dispatcher. The dispatcher acts as a proxy and
|
|
// waits for the server and the clients to register. There can only be one
|
|
// server registered, with multiple clients requesting connections to the
|
|
// server. For each client, the dispatcher is responsible for creating a Mojo
|
|
// channel to the server and pass the established Mojo channel to the client in
|
|
// order to set up a Mojo channel between the client and the server.
|
|
//
|
|
// The CameraHalDispatcher is designed to help the server and the clients to
|
|
// recover from errors easily. For example, when the camera HAL process crashes
|
|
// the CameraHalDispatcher can still hold the connections of the clients. When
|
|
// the camera HAL reconnects the CameraHalDispatcher can then quickly restore
|
|
// the Mojo channels between the clients and the camera HAL process by calling
|
|
// CameraHalClient::SetUpChannel() in RegiserServer().
