Method Detail

invalidateKey

public void invalidateKey(java.lang.String cacheName,
                          java.io.Serializable key)

Invalidate a key in the cache. Note that the key must be Serializable, as it may be sent to several clustered servers. It is also strongly urged (if not required) that the key implement hashcode() and equals() in such a way that the serialized key will match the intended key in the cache.

This method will remove the key for all instances of the named cache. It sends a notification to all registered CacheNotificationListeners, who will in turn notify their associated Cache objects to invalidate this key.

These listeners are created by the CacheFactory object and registered with the CacheManagerMBean. Notifications are sent and tagged with the cache name.

A dynamic MBean attribute

Parameters:

cacheName - The name of the cache to update

key - the key of a key/value pair to in the cache to invalidate

flushCache

public void flushCache(java.lang.String cacheName)

Flush all instances of this named cache. Send a notification to all registered CacheNotificationListeners, who will in turn notify their associated Cache objects to flush.

These listeners are created by the CacheFactory object and registered with the CacheManagerMBean. Notifications are sent and tagged with the cache name.

A dynamic MBean attribute

Parameters:

cacheName - The name of the cache to flush
