Constructor Detail

ExpiryCountingLocalCache

public ExpiryCountingLocalCache()

Construct the cache manager.

ExpiryCountingLocalCache

public ExpiryCountingLocalCache(int cUnits)

Construct the cache manager.

Parameters:

cUnits - the number of units that the cache manager will cache before pruning the cache

ExpiryCountingLocalCache

public ExpiryCountingLocalCache(int cUnits,
                                int cExpiryMillis)

Construct the cache manager.

Parameters:

cUnits - the number of units that the cache manager will cache before pruning the cache

cExpiryMillis - the number of milliseconds that each cache entry lives before being automatically expired

ExpiryCountingLocalCache

public ExpiryCountingLocalCache(int cUnits,
                                int cExpiryMillis,
                                com.tangosol.net.cache.CacheLoader loader)

Construct the cache manager.

Parameters:

cUnits - the number of units that the cache manager will cache before pruning the cache

cExpiryMillis - the number of milliseconds that each cache entry lives before being automatically expired

loader - the CacheLoader or CacheStore to use

Method Detail

removeExpired

protected void removeExpired(com.tangosol.net.cache.OldCache.Entry entry,
                             boolean fRemoveInternal)

Remove an entry because it has expired and increment the count of expired entries.

Parameters:

entry - the expired cache entry

fRemoveInternal - true if the cache entry still needs to be removed from the cache

getExpiryCount

public long getExpiryCount()

Returns the number of entries expired by the cache.
