Constructor Detail

CacheManagerSamplerImpl

public CacheManagerSamplerImpl(CacheManager cacheManager)
Constructor taking the backing CacheManager

Parameters:
cacheManager - to wrap
Method Detail

clearAll

public void clearAll()
Clears the contents of all caches in the CacheManager, but without removing any caches.

This method is not synchronized. It only guarantees to clear those elements in a cache at the time that the Ehcache.removeAll() mehod on each cache is called.

Specified by:
clearAll in interface CacheManagerSampler

getCacheNames

public String[] getCacheNames()
                       throws IllegalStateException
Gets the cache names managed by the CacheManager

Specified by:
getCacheNames in interface CacheManagerSampler
Throws:
IllegalStateException

getStatus

public String getStatus()
Gets the status attribute of the Ehcache

Specified by:
getStatus in interface CacheManagerSampler
Returns:
The status value, as a String from the Status enum class

shutdown

public void shutdown()
Shuts down the CacheManager.

If the shutdown occurs on the singleton, then the singleton is removed, so that if a singleton access method is called, a new singleton will be created.

Specified by:
shutdown in interface CacheManagerSampler
