How to clear entire cache manager?

[amalrajvinoth]

Dear All,

How to clear entire cachemanager

For ex: clearing all caches associated with cache manager & their cache  entries.

thanks,

amal.

refering to  the api of  DefaultCacheManager :

When the system shuts down, it should call stop() on the CacheManager. This will ensure all caches within its scope are properly stopped as well

but this is only work for single JVM and all caches is still available for other node if u use cluster。

if u dont want stop the CacheManager and just want to clear all the entries , i think u can get all the caches  and invoke the clear() method for each.

    Set<String> set =  cacheManager.getCacheNames();
      Iterator<String> iterator =  set.iterator();
      while(iterator.hasNext()){
          String cacheName = iterator.next();
          Cache<String,Object> cache = cacheManager.getCache(cacheName);
          cache.clear();
      }

In forthcoming 5.0.0.Beta1, you'll be able to remove a cache cluster wide via removeCache() call in EmbeddedCacheManager - https://issues.jboss.org/browse/ISPN-905

Note that jombo's suggestion will only clear the named caches defined in the XML or programmatically via defineConfiguration() method because getCacheNames() is limited to returning that. This won't return all running caches in that cache manager. In fact, probably a getRunningCacheNames() is needed to provide all names of caches running, both predefined, and the ones generated at runtime based on the default configuation (i.e. when getCache(name) is called and that cache is not within the named or defined ones). I'll start a dev list to discuss this.

Btw, I've created a discussion around my last comment in http://lists.jboss.org/pipermail/infinispan-dev/2011-March/007579.html - in case you wanna chip in

[jombo]

it seems that i dont understand this method clearly. sorry to amal

Jombo, your suggestion will work as expected since https://issues.jboss.org/browse/ISPN-981 was resolved.
