Interface OgnlCache<K,V>

Type Parameters:
K - The type for the cache key entries
V - The type for the cache value entries
All Known Implementing Classes:
OgnlCaffeineCache, OgnlDefaultCache, OgnlLRUCache
public interface OgnlCache<K,V>
A basic cache interface for use with OGNL processing (such as Expression, BeanInfo). Implementation must be thread-safe. All OGNL caches will have an eviction limit, but setting an extremely high value can simulate an "effectively unlimited" cache.
