Method Detail

getExtCacheEntry

ExtCacheEntry<K,V> getExtCacheEntry(K key)

Returns the extended entry

compareVersionAndPut

boolean compareVersionAndPut(K key,
                             long version,
                             java.lang.Object value)

Updates the cache if the old value hash matches the current value. A null value for the old value hash only adds the entry if it's new

Parameters:

key - the key to compare

version - the version of the old value returned by getEntry

value - the new value

Returns:

true if the update succeeds, false if it fails

compareAndRemove

boolean compareAndRemove(K key,
                         long version)

Removes the entry from the cache if the current entry's version matches.

isClosed

boolean isClosed()

Returns true if the cache is closed

getStatCacheEntry

ExtCacheEntry<K,V> getStatCacheEntry(K key)
