sum

public CameraMetrics sum(CameraMetrics b,
                         CameraMetrics output)

For convenience, this function accepts null values and will allocate an output object if none is passed in.

Specified by:

sum in class SystemMetrics<CameraMetrics>

Returns:

output set to (this + b)

diff

public CameraMetrics diff(CameraMetrics b,
                          CameraMetrics output)

Description copied from class: SystemMetrics

Subtract the object passed in from the current object. Does not modify the original object.

For convenience, this function accepts null values and will allocate an output object if none is passed in.
