Remarks

This class contains window content frame statistics. For example, a window content is rendred in frames when a view is scrolled. The frame statistics are a snapshot for the time interval from #getStartTimeNano() to #getEndTimeNano().

The key idea is that in order to provide a smooth user experience an application has to draw a frame at a specific time interval obtained by calling #getRefreshPeriodNano(). If the application does not render a frame every refresh period the user will see irregular UI transitions.

An application posts a frame for presentation by synchronously rendering its contents in a buffer which is then posted or posting a buffer to which the application is asychronously rendering the content via GL. After the frame is posted and rendered (potentially asynchronosly) it is presented to the user. The time a frame was posted can be obtained via #getFramePostedTimeNano(int), the time a frame content was rendered and ready for dsiplay (GL case) via #getFrameReadyTimeNano(int), and the time a frame was presented on the screen via #getFramePresentedTimeNano(int).
