Javadoc

PUBLIC: A CacheInvalidationPolicy which allows objects to live for a specific amount of time after they are read. A TimeToLiveCacheInvalidationPolicy is instantiated with a specific number of milliseconds. This represents how long after an object is read it will expire.

Most used methods

getExpiryTimeInMillis
INTERNAL: Return the next expiry time.
getTimeToLive
PUBLIC: Return the time-to-live specified for this policy.
