K - the key type for the cacheV - the value type for the cacheExpiryPolicy that builds on the java.time types.@Deprecated
public interface Expiry<K,V>
Cache.
Previous values are not accessible directly but are rather available through a value supplier
to indicate that access can require computation (such as deserialization).
NOTE: Some cache configurations (eg. caches with eventual consistency) may use local (ie. non-consistent) state
to decide whether to call getExpiryForUpdate(Object, org.ehcache.ValueSupplier, Object) vs.
getExpiryForCreation(Object, Object). For these cache configurations it is advised to return the same
value for both of these methods
See Expirations for helper methods to create common Expiry instances.

This method must not return null.
Exceptions thrown from this method will be swallowed and result in the expiry duration being
ZERO.
key - the key of the newly added entryvalue - the value of the newly added entryDurationDuration getExpiryForAccess(K key, ValueSupplier<? extends V> value)
Duration (relative to the current time) when an existing entry is accessed from a
Cache.
Returning null indicates that the expiration time remains unchanged.
Exceptions thrown from this method will be swallowed and result in the expiry duration being
ZERO.
key - the key of the accessed entryvalue - a value supplier for the accessed entryDuration, null means unchangedDuration getExpiryForUpdate(K key, ValueSupplier<? extends V> oldValue, V newValue)
Duration (relative to the current time) when an existing entry is updated in a
Cache.
Returning null indicates that the expiration time remains unchanged.
Exceptions thrown from this method will be swallowed and result in the expiry duration being
ZERO.
