Package org.hibernate.cache.internal

Class CacheKeyImplementation

java.lang.Object

org.hibernate.cache.internal.CacheKeyImplementation

All Implemented Interfaces:

Serializable

@Internal
public final class CacheKeyImplementation
extends Object
implements Serializable

Allows multiple entity classes / collection roles to be stored in the same cache region. Also allows for composite keys which do not properly implement equals()/hashCode(). This was named org.hibernate.cache.spi.CacheKey in Hibernate until version 5. Temporarily maintained as a reference while all components catch up with the refactoring to the caching interfaces.
