Method Detail
-
setCacheImage
public void setCacheImage(boolean cacheImage)
Sets image caching policy. If true, plot image will be cached where applicable, if false it will be regenerated from the data on every repaint.- Parameters:
cacheImage
- image caching policy
-
getCacheImage
public boolean getCacheImage()
Returns images caching policy. If true, plot image will be cached where applicable, if false it will be regenerated from the data on every repaint.- Returns:
- image caching policy
-
setReuseRanges
public void setReuseRanges(boolean reuseRanges)
Sets aux range caching policy. If true, aux ranges will be calculated only once, if false they will be recalculated when the surface changes.- Parameters:
reuseRanges
- aux range caching policy
-
getReuseRanges
public boolean getReuseRanges()
Returns the aux range caching policy. If true, aux ranges will be calculated only once, if false they will be recalculated when the surface changes.- Returns:
- aux range caching policy
-
setUsePlans
public void setUsePlans(boolean usePlans)
Sets plan caching policy. If true, plan objects will be retained following a plot and used as input to the next plotting attempt; if false, no plans will be cached.- Parameters:
usePlans
- drawing plan caching policy- See Also:
Drawing.calculatePlan(java.lang.Object[], uk.ac.starlink.ttools.plot2.data.DataStore)
-
getUsePlans
public boolean getUsePlans()
Returns the plan caching policy. If true, plan objects will be retained following a plot and used as input to the next plotting attempt; if false, no plans will be cached.- Returns:
- drawing plan caching policy
- See Also:
Drawing.calculatePlan(java.lang.Object[], uk.ac.starlink.ttools.plot2.data.DataStore)
-
createFullyCached
public static PlotCaching createFullyCached()
Returns an instance in which as much as possible is cached between plot frames.- Returns:
- aggressively caching instance
-
createUncached
public static PlotCaching createUncached()
Returns an instance in which nothing is cached between plot frames.- Returns:
- non-caching instance
