{code}$cache = CFactory::getCache('Core');
// Random is to handle shuffle matter,
// cache 3 different set of data.
$intRandom = rand(COMMUNITY_CACHE_RANDOM_MIN,

Cache Implement / Remove In Model Class
1. To implement cache in model class, add following code in constructor
// addMethod(methodName, [ACTION_SAVE, ACTION_REMOVE], [COMMUNITY_CACHE_TAG_ALL, array(TAG)])
$oCache = CCache::inject($this);
$oCache->addMethod('getAllPhotos', CCache::ACTION_SAVE, array(COMMUNITY_CACHE_TAG_PHOTOS));
2. To remove cache in model class, add following code in models's constructor
$oCache = CCache::inject($this);
$oCache->addMethod('deleteActivity', CCache::ACTION_REMOVE, array(COMMUNITY_CACHE_TAG_ACTIVITIES));
$oCache->addMethod('removeActivity', CCache::ACTION_REMOVE, array(COMMUNITY_CACHE_TAG_ACTIVITIES));
Cache Remove In Table Class
1. Extend CTableCache (table/cache.php) in table class
class CTablePhoto extends CTableCache
2. Add following code in constructor
// Get cache object.
$oCache = CCache::inject($this);
// Remove video cache on every delete & store
$oCache->addMethod(CCache::METHOD_DEL, CCache::ACTION_REMOVE, array(COMMUNITY_CACHE_TAG_VIDEOS));
$oCache->addMethod(CCache::METHOD_STORE, CCache::ACTION_REMOVE, array(COMMUNITY_CACHE_TAG_VIDEOS));
// Only CCache::METHOD_DEL, CCache::METHOD_SAVE, CCache::METHOD_STORE will handle by
// the cache object,other methods need to be done manually by the class itself.
