Method Detail

remove

void remove(K key)
            throws IOException

Removes the Entry

Parameters:

key -

Throws:

IOException

updateExpirationTimestamp

void updateExpirationTimestamp(K key,
                             long expirationTimestamp)

Will be called to update an expiration timestamp. Should not throw an exception, because we assume that expiration timestamp will always be extended to a date longer in the future. Therefore on failing the old expiration will not be renewed and the cache entry will expire. Hence in worst case retrieving the value from server will be needed. That's acceptable.

Parameters:

key -

expirationTimestamp -
