Interface Cache<KeyType extends Serializable,ValueType extends Serializable>

All Known Implementing Classes:

EhCache, ForeverCache, ZeroCache

public interface Cache<KeyType extends Serializable,ValueType extends Serializable>

The Cache interface represents a cache intended for application-level caching. In some circumstances it is more optimal to implement caching directly in the code instead of relying on Hibernate caching methods. This interface abstracts from the used cache implementation. Cache implementations must be thread-safe.
