/**
* Denotes that the annotated method uses the experimental methods which allow direct access to
* camera2 classes.
*
* <p>The Camera2Interop and Camera2Interop.Extender exposes the underlying instances of camera2
* classes such CameraDevice.StateCallback, CameraCaptureSession.StateCallback and
* CameraCaptureSession.CaptureCallback. In addition the configs allow setting of camera2
* CaptureRequest parameters. However, CameraX does not provide any guarantee on how it operates
* on these parameters. The ordering and number of times these objects might in order to best
* optimize the top level behavior.
*
* <p>The values from the callbacks should only be read. Methods that modify the CameraDevice or
* CameraCaptureSession will likely move CameraX into an inconsistent internal state.
*
* <p>These will be changed in future release possibly, hence add @Experimental annotation.
