Additional Methods

In addition to the operations explained in the Async Operations section and Custom ExpiryPolicy section, Hazelcast ICache also provides a set of convenience methods. These methods are not part of the JCache specification.

  • size(): Returns the estimated size of the distributed cache.
  • destroy(): Destroys the cache and removes the data from memory. This is different from the method javax.cache.Cache::close.
  • getLocalCacheStatistics(): Returns a com.hazelcast.cache.CacheStatistics instance providing the same statistics data as the JMX beans. This method is not available yet on Hazelcast clients: the exception java.lang.UnsupportedOperationException is thrown when you use this method on a Hazelcast client.
