org.broadleafcommerce.common.extensibility.cache.ehcache.DefaultExpiryPolicy

All Implemented Interfaces:

org.ehcache.expiry.ExpiryPolicy<Object,Object>

InfiniteExpiryPolicy, OneHourExpiryPolicy, OneMinuteExpiryPolicy, TenMinuteExpiryPolicy, ThirtyMinuteExpiryPolicy, TwelveHourExpiryPolicy, TwentyFourHourExpiryPolicy

public class DefaultExpiryPolicy
extends Object
implements org.ehcache.expiry.ExpiryPolicy<Object,Object>

Defines a default ExpiryPolicy for EhCache. In particular, this takes a TTL in seconds and converts it to a Cache duration or TTL. This provides both a default TTL for caches created with it programmatically, as well as a way of mapping per-entry TTL values in EhCache when the cached value is an instance of TimedValueHolder.
