CacheKeyImplementation (Hibernate JavaDocs)

java.lang.Object
- org.hibernate.cache.internal.CacheKeyImplementation

All Implemented Interfaces:

Serializable
```
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.

    id - The identifier associated with the cached data
    
    type - The Hibernate type mapping
