public CacheKey(Serializable id, org.hibernate.type.Type type, String entityOrRoleName, org.hibernate.EntityMode entityMode, org.hibernate.engine.SessionFactoryImplementor factory)
Construct a new key for a collection or entity instance. Note that an entity name should always be the root entity name, not a subclass entity name.

id The identifier associated with the cached data
param
type The Hibernate type mapping
param
entityOrRoleName The entity or collection-role name.
param
entityMode The entiyt mode of the originating session
param
factory The session factory for which we are caching
