      • getCurrentNumberOfEntries

        public int getCurrentNumberOfEntries()
        Description copied from interface: Stats
        Returns the number of entries currently in this cache instance. When the cache is configured with distribution, this method only returns the number of entries in the local cache instance. In other words, it does not attempt to communicate with other nodes to find out about the data stored in other nodes in the cluster that is not available locally.
        Specified by:
        getCurrentNumberOfEntries in interface Stats
        Returns:
        Number of entries currently in the cache, including passivated entries.

      • getTotalNumberOfEntries

        public long getTotalNumberOfEntries()
        Description copied from interface: Stats
        Number of entries stored in cache since the cache started running.
        Specified by:
        getTotalNumberOfEntries in interface Stats

        Specified by:
        getDataMemoryUsed in interface Stats
        Returns:
        memory in use or 0 if memory eviction is not enabled
