Interface OgnlCache<Key,Value>

Type Parameters:

Key - The type for the cache key entries

Value - The type for the cache value entries

All Known Implementing Classes:

OgnlCaffeineCache, OgnlDefaultCache, OgnlLRUCache

public interface OgnlCache<Key,Value>

A basic cache interface for use with OGNL processing (such as Expression, BeanInfo). All OGNL caches will have an eviction limit, but setting an extremely high value can simulate an "effectively unlimited" cache.
