    Description copied from interface: Cache.Listener
    
    Called when a CacheSpan is added to the cache.
    
    Specified by:
    
    onSpanAdded in interface Cache.Listener
    
    Parameters:
    
    cache - The source of the event.
    
    span - The added CacheSpan.
  - onSpanRemoved

public void onSpanRemoved(Cache cache,
                          CacheSpan span)
```
    Deprecated.
    
    Description copied from interface: Cache.Listener

    Specified by:

    Parameters:
    
    cache - The source of the event.
    
    span - The removed CacheSpan.
  - onSpanTouched
```
public void onSpanTouched(Cache cache,

```
    Deprecated.
    
    Description copied from interface: Cache.Listener
    
    Called when an existing CacheSpan is touched, causing it to be replaced. The new CacheSpan is guaranteed to represent the same data as the one it replaces, however CacheSpan.file and CacheSpan.lastTouchTimestamp may have changed.
    Note that for span replacement, Cache.Listener.onSpanAdded(Cache, CacheSpan) and Cache.Listener.onSpanRemoved(Cache, CacheSpan) are not called in addition to this method.

    Parameters:
    
    cache - The source of the event.
    
    oldSpan - The old CacheSpan, which has been removed from the cache.
    
    newSpan - The new CacheSpan, which has been added to the cache.
