protected long[]	mFramesPresentedTimeNano

Constructors Summary

Methods Summary
public final long	getEndTimeNano() 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 The end time in nanoseconds or {@link #UNDEFINED_TIME_NANO} if there is no frame data. if (getFrameCount() <= 0) { return UNDEFINED_TIME_NANO; } return mFramesPresentedTimeNano[mFramesPresentedTimeNano.length - 1];
public final int	getFrameCount() Gets the number of frames for which there is data. return The number of frames. return mFramesPresentedTimeNano != null ? mFramesPresentedTimeNano.length : 0;
public final long	getFramePresentedTimeNano(int index) Get the time a frame at a given index was presented. param index The frame index. return The presented time in nanoseconds or {@link #UNDEFINED_TIME_NANO} if the frame is not presented yet. if (mFramesPresentedTimeNano == null) { throw new IndexOutOfBoundsException(); } return mFramesPresentedTimeNano[index];
public final long	getRefreshPeriodNano() Gets the refresh period of the display hosting the window(s) for which these statistics apply. return The refresh period in nanoseconds. return mRefreshPeriodNano;
public final long	getStartTimeNano() 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 The start time in nanoseconds or {@link #UNDEFINED_TIME_NANO} if there is no frame data. if (getFrameCount() <= 0) { return UNDEFINED_TIME_NANO; } return mFramesPresentedTimeNano[0];
