public class HibernateCacheLoader
Data-driven CacheLoader implementation for Hibernate tables <p/> These methods all follow the pattern of:
Field Summary | |
---|---|
protected static String |
PARAM_IDS Name of the "ids" named parameter in HQL bulk queries |
Constructor Summary | |
---|---|
HibernateCacheLoader() Default constructor. |
|
HibernateCacheLoader(String sEntityName) Constructor which accepts an entityName. |
|
HibernateCacheLoader(String sEntityName, File configurationFile) Constructor which accepts an entityName and a Hibernate configuration resource. |
|
HibernateCacheLoader(String sEntityName, String sResource) Constructor which accepts an entityName and a Hibernate configuration resource. |
Method Summary | |
---|---|
protected void |
closeSession(Session session) Close a Hibernate Session. |
protected Object |
createEntityFromId(Object id) Create a transient entity instance given an entity id |
protected void |
ensureInitialized() Called by all API-implementing methods for lazy initialization. |
protected ClassMetadata |
getEntityClassMetadata() Get the Hibernate ClassMetadata for the Hibernate entity |
protected String |
getEntityName() Get the Hibernate entity name |
protected String |
getLoadAllQuery() Get the parameterized loadAll HQL query string |
SessionFactory |
getSessionFactory() Get the Hibernate SessionFactory. |
protected void |
initialize() Initializer (must be called post-constructor) <p/> We do this specifically so that derived classes can safely create override methods that depend on a fully constructed object state. |
Object |
load(Object key) Load a Hibernate entity given an id (key) |
Map |
loadAll(Collection keys) Load a collection of Hibernate entities given a set of ids (keys) |
protected Session |
openSession() Open a Hibernate Session. |
protected void |
setEntityClassMetadata(ClassMetadata entityClassMetadata) Get the Hibernate ClassMetadata for the Hibernate entity |
void |
setEntityName(String sEntityName) Set the Hibernate entity name. |
protected void |
setLoadAllQuery(String sLoadAllQuery) Get the parameterized loadAll HQL query string |
void |
setSessionFactory(SessionFactory sessionFactory) Set the Hibernate SessionFactory to be used by this CacheLoader. |
protected void |
validateIdentifier(Serializable id, Object entity) Ensure that there are no conflicts between an explicit and implicit key. |
