Hazelcast JCache Hazelcast JCache Extension-ICache ICache Convenience Methods

In addition to the operations explained in ICache Async Methods and Defining a Custom ExpiryPolicy, 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.
