java.lang.Object
org.jzy3d.chart.controllers.RateLimiterByMilisecond
org.jzy3d.chart.controllers.RateLimiterAdaptsToRenderTime
All Implemented Interfaces:
RateLimiter
public class RateLimiterAdaptsToRenderTime extends RateLimiterByMilisecond implements RateLimiter
This rate limiter keeps an history of past rendering time to auto configure the rate limit and ensure we stick to actual rendering time before doing an action. This rate limiter is useful to ensure a controller such as mouse or thread won't ask more rendering than possible. The time limit is computed as follow
  • Compute the maximum rendering time in the list of the 10 last rendering time
  • Adds a 20ms margin
This allows adapting the rate limit if the rendering capabilities changes, which may happen according to a changing canvas size, changing screen, changing HiDPI settings, changing content of chart.
