  - maxCacheSize
```
protected int maxCacheSize
```
    Maximum size in bytes that the cache can grow to.
  - cacheSize
```
protected int cacheSize
```
    Maintains the current size of the cache in bytes.
  - maxLifetime
```
protected long maxLifetime
```
    Maximum length of time objects can exist in cache before expiring.
  - cacheHits
```
protected long cacheHits
```
    Maintain the number of cache hits and misses. A cache hit occurs every time the get method is called and the cache contains the requested object. A cache miss represents the opposite occurence.
    
    Keeping track of cache hits and misses lets one measure how efficient the cache is; the higher the percentage of hits, the more efficient.
  - cacheMisses
```
protected long cacheMisses
```
    Maintain the number of cache hits and misses. A cache hit occurs every time the get method is called and the cache contains the requested object. A cache miss represents the opposite occurence.
    
    Keeping track of cache hits and misses lets one measure how efficient the cache is; the higher the percentage of hits, the more efficient.
  - name
```
protected String name
```
    The name of the cache.
  - isStopPutWhenFull

    从接口复制的说明: Cache
    
    Removes all cached datas from this cache (optional operation).
    
    指定者:
    
    clear 在接口中 Cache<K,V>
    
    指定者:
    
    clear 在接口中 Map<K,V>
  - getCacheHits
```
public long getCacheHits()
```
    从接口复制的说明: Cache
    
    Returns the number of cache hits. A cache hit occurs every time the get method is called and the cache contains the requested object.
    Keeping track of cache hits and misses lets one measure how efficient the cache is; the higher the percentage of hits, the more efficient.
    
    指定者:
    
    getCacheHits 在接口中 Cache<K,V>
    
    返回:
    
    the number of cache hits.
  - getCacheMisses
```

```
    从接口复制的说明: Cache
    
    Returns the number of cache misses. A cache miss occurs every time the get method is called and the cache does not contain the requested object.
    Keeping track of cache hits and misses lets one measure how efficient the cache is; the higher the percentage of hits, the more efficient.
    
    指定者:

    返回:
    
    the number of cache hits.
  - getCacheSize
```
public int getCacheSize()
```
    从接口复制的说明: Cache
    
    Returns the size of the cache contents in bytes. This value is only a rough approximation, so cache users should expect that actual VM memory used by the cache could be significantly higher than the value reported by this method.
    
    指定者:
    
    getCacheSize 在接口中 Cache<K,V>
    
    返回:
    
    the size of the cache contents in bytes.
  - getMaxCacheSize
```
public int getMaxCacheSize()
```
    从接口复制的说明: Cache
    
    Returns the maximum size of the cache in bytes. If the cache grows larger than the max size, the least frequently used items will be removed. If the max cache size is set to -1, there is no size limit.
    
    指定者:
    
    getMaxCacheSize 在接口中 Cache<K,V>
    
    返回:
    
    the maximum size of the cache in bytes.
  - getMaxLifetime
```
public long getMaxLifetime()
```
    从接口复制的说明: Cache
    
    Returns the maximum number of milleseconds that any object can live in cache. Once the specified number of milleseconds passes, the object will be automatically expried from cache. If the max lifetime is set to -1, then objects never expire.
    
    指定者:
    
    getMaxLifetime 在接口中 Cache<K,V>
    
    返回:
    
    the maximum number of milleseconds before objects are expired.
