public static Stats create(Configuration configuration,
                           AsyncInterceptorChain chain)
```
    Use this factory to create Stats object from configuration and the interceptor chain.
    
    Parameters:
    
    configuration -
    
    chain -
    
    Returns:
    
    Stats object
  - create
```
public static Stats create(StatsCollector collector)
```
    Use this factory to create Stats object from StatsCollector.
    
    Parameters:
    
    collector -
    
    Returns:
  - getTimeSinceStart
```
public long getTimeSinceStart()
```
    Specified by:
    
    getTimeSinceStart in interface Stats
    
    Returns:
    
    Number of seconds since cache started.
  - getTimeSinceReset
```
public long getTimeSinceReset()
```
    Specified by:
    
    getTimeSinceReset in interface Stats
    
    Returns:
    
    Number of seconds since stats where reset
  - 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.
  - getCurrentNumberOfEntriesInMemory
```
public int getCurrentNumberOfEntriesInMemory()
```
    Description copied from interface: Stats
    
    The same as Stats.getCurrentNumberOfEntries(), however passivated entries are not included.
    
    Specified by:
    
    getCurrentNumberOfEntriesInMemory in interface Stats
  - 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
  - getDataMemoryUsed
```
public long getDataMemoryUsed()
```
    Description copied from interface: Stats
    
    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:
    
    getDataMemoryUsed in interface Stats
    
    Returns:
    
    memory in use or 0 if memory eviction is not enabled
