Class AnnotationUsageCache

java.lang.Object

com.helger.commons.cache.AnnotationUsageCache

All Implemented Interfaces:

Serializable

@ThreadSafe
public class AnnotationUsageCache
extends Object
implements Serializable

A simple cache for the usage of a certain annotation class at other classes.
Note: cannot use AbstractNotifyingCache because it would need a Class<?> as a key and this would be a hard wired reference.
