Class ComputingCache<K,V>

java.lang.Object

io.quarkus.arc.impl.ComputingCache<K,V>

Type Parameters:

K -

V -

public class ComputingCache<K,V>
extends Object

Computing cache backed by a ConcurrentHashMap which intentionally does not use Map.computeIfAbsent(Object, Function) and is reentrant. Derived from org.jboss.weld.util.cache.ReentrantMapBackedComputingCache.
