Class PainterCache<K,V>

java.lang.Object

com.metsci.glimpse.core.support.PainterCache<K,V>

public class PainterCache<K,V>
extends Object

Provides one way of asynchronously computing a long-running task for painting. For example:

 
 public class MyPainter extends GlimpsePainterBase
 {
     int paintFrame;
     PaintingCache<Integer, V> cache;

     public MyPainter( )
     {
         paintFrame = -1;
         cache = new PaintingCache<>( this::computeForFrame );
     }
