class SessionParametersCompat

A compat class to store Session Parameters for querying support. This class is a simple holder class for holding CaptureRequest.Keys and associated values, similar to what CaptureRequest does in setSessionParameters.

This class must not be used for camera devices that support android.hardware.camera2.CameraDevice.CameraDeviceSetup. For device that support android.hardware.camera2.CameraDevice.CameraDeviceSetup, use createCaptureRequest for session parameters instead.
