Examples of org.infinispan.DecoratedCache

org.infinispan.DecoratedCache
A decorator to a cache, which can be built with a specific {@link ClassLoader} and a set of {@link Flag}s. This {@link ClassLoader} and set of {@link Flag}s will be applied to all cache invocations made via this decorator.
In addition to cleaner and more readable code, this approach offers a performance benefit to using {@link AdvancedCache#with(ClassLoader)} or {@link AdvancedCache#withFlags(org.infinispan.context.Flag)} APIs, thanks tointernal optimizations that can be made when the {@link ClassLoader} and {@link Flag} set is unchanging. @author Manik Surtani @author Sanne Grinovero @see AdvancedCache#with(ClassLoader) @see AdvancedCache#withFlags(org.infinispan.context.Flag) @since 5.1


   public static <K, V> CacheAdapter<K, V> createAdapter(AdvancedCache<K, V> advancedCache, TreeContextContainer tcc) {
      if (advancedCache instanceof CacheAdapter) {
         return (CacheAdapter<K, V>) advancedCache;
      } else if (advancedCache instanceof DecoratedCache) {
         DecoratedCache dc = (DecoratedCache) advancedCache;
         Cache<K, V> delegate = dc.getDelegate();
         if (delegate instanceof AdvancedCache)
            return new DecoratedCacheAdapter<K, V>((AdvancedCache) delegate, tcc, dc.getFlags());
