/**
* When a method annotated with {@link CacheRemoveAll} is invoked all elements in
* the specified cache will be removed via the
* {@link javax.cache.Cache#removeAll()} method
*
* The default behavior is to call {@link javax.cache.Cache#removeAll()} after the
* annotated method is invoked, this behavior can be changed by setting {@link
* #afterInvocation()} to false in which case {@link javax.cache.Cache#removeAll()}
* will be called before the annotated method is invoked.
*
* Example of removing all Domain objects from the "domainCache". {@link
* javax.cache.Cache#removeAll()} will be called after deleteAllDomains() returns
* successfully.
*
* package my.app;
*
* public class DomainDao {
* @CacheRemoveAll(cacheName="domainCache")
* public void deleteAllDomains() {
* ...
* }
* }
*
* Exception Handling, only used if {@link #afterInvocation()} is true.
*
* - If {@link #evictFor()} and {@link #noEvictFor()} are both empty then all
* exceptions prevent the removeAll
* - If {@link #evictFor()} is specified and {@link #noEvictFor()} is not
* specified then only exceptions which pass an instanceof check against the
* evictFor list result in a removeAll
* - If {@link #noEvictFor()} is specified and {@link #evictFor()} is not
* specified then all exceptions which do not pass an instanceof check against the
* noEvictFor result in a removeAll
* - If {@link #evictFor()} and {@link #noEvictFor()} are both specified then
* exceptions which pass an instanceof check against the evictFor list but do not
* pass an instanceof check against the noEvictFor list result in a removeAll
