public abstract List<Camera2CameraInfo> filter (List<Camera2CameraInfo> cameraInfos)
Filters a list of Camera2CameraInfo then returns those matching the requirements.
If the output list contains Camera2CameraInfo not in the input list, when used by a
CameraSelector then it will result in an
IllegalArgumentException thrown when calling bindToLifecycle.
The Camera2CameraInfo that has lower index in the map has higher priority. When
used by
CameraSelector.Builder.addCameraFilter(CameraFilter), the
available cameras will be filtered by the Camera2CameraFilter.Camera2Filter and all other
CameraFilters by the order they were added. The first camera in the result
will be selected if there are multiple cameras left.

| Returns | |
|---|---|
List<Camera2CameraInfo> |
The output map of camera IDs and their CameraCharacteristics that
match the requirements. Users are expected to create a new map to return with.
