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.

Provides how much memory the current eviction algorithm estimates is in use for data. This method will return a number 0 or greater if memory eviction is in use. If memory eviction is not enabled this method will always return 0.

Specified by:
