Public methods

fromCameraInfo

public static Camera2CameraInfo fromCameraInfo (CameraInfo cameraInfo)

Gets the Camera2CameraInfo from a CameraInfo.

Parameters
`cameraInfo`	`CameraInfo`: The `CameraInfo` to get from.

Returns
`Camera2CameraInfo`	The camera information with Camera2 implementation.

Throws
`IllegalStateException`	if the camera info does not contain the camera2 information (e.g., if CameraX was not initialized with a `Camera2Config`).

getCameraCharacteristic

public T getCameraCharacteristic (Key<T> key)

Gets a camera characteristic value.

The characteristic value is the same as the value in the CameraCharacteristics that would be obtained from CameraManager.getCameraCharacteristics(String).

Parameters
`key`	`Key`: The `CameraCharacteristics.Key` of the characteristic.

Returns
`T`	the value of the characteristic.

getCameraId

public String getCameraId ()

Gets the string camera ID.

The camera ID is the same as the camera ID that would be obtained from CameraManager.getCameraIdList(). The ID that is retrieved is not static and can change depending on the current internal configuration of the Camera from which the CameraInfo was retrieved. The Camera is a logical camera which can be backed by multiple CameraDevice. However, only one CameraDevice is active at one time. When the CameraDevice changes then the camera id will change.

Returns
`String`	the camera ID.

Throws
`IllegalStateException`	if the camera info does not contain the camera 2 camera ID (e.g., if CameraX was not initialized with a `Camera2Config`).
