FrameStats()

fun getEndTimeNano(): Long

Gets the end time of the interval for which these statistics apply. The end interval is the time when the last frame was presented.

Return
`Long`	The end time in nanoseconds or `UNDEFINED_TIME_NANO` if there is no frame data.

fun getFrameCount(): Int

Gets the number of frames for which there is data.

Return
`Int`	The number of frames.

fun getFramePresentedTimeNano(index: Int): Long

Get the time a frame at a given index was presented.

Parameters
`index`	Int: The frame index.

Return
`Long`	The presented time in nanoseconds or `UNDEFINED_TIME_NANO` if the frame is not presented yet.

fun getRefreshPeriodNano(): Long

Gets the refresh period of the display hosting the window(s) for which these statistics apply.

Return
`Long`	The refresh period in nanoseconds.

fun getStartTimeNano(): Long

Gets the start time of the interval for which these statistics apply. The start interval is the time when the first frame was presented.

Return
`Long`	The start time in nanoseconds or `UNDEFINED_TIME_NANO` if there is no frame data.
