public abstract class GenericHibernateManualUpdateDao<T,ID extends Serializable>
extends Object

Implements the generic CRUD data access operations using Hibernate APIs.

The instances returned by this class do not automatically persist changes to its state. The method update(Object, ITransaction) must be called to do it.

To write a DAO, subclass and parameterize this class with your persistent class. Of course, assuming that you have a traditional 1:1 approach for Entity:DAO design.

You have to inject the Class object of the persistent class to construct a DAO.

Since:
4.0.11

Constructor Detail

GenericHibernateManualUpdateDao

protected GenericHibernateManualUpdateDao(Class<T> persistentClass)
Method Detail

getIdentifier

protected abstract ID getIdentifier(T bean)

getPersistentClass

protected Class<T> getPersistentClass()
Returns the class whose persistence this DAO controls.


get

protected T get(ID id,
                ITransaction transaction)
         throws PortalObjectNotFoundException,
                PortalException
Returns the bean with the given id. The bean is set as read-only, so changes on it won't persist automatically.

Parameters:
id - the bean's id.
transaction - the transaction for persistence access. Must be a ITransactionHibernate.
Returns:
the bean.
Throws:
PortalObjectNotFoundException - if the corresponding bean does not exist in the persistence.
PortalException

add

protected void add(T bean,
                   ITransaction transaction)
            throws PortalException
Adds the bean to the persistence layer.

Parameters:
bean - the bean to be added.
transaction - the transaction for persistence access.
Throws:
PortalException

update

protected void update(T bean,
                      ITransaction transaction)
               throws PortalException
Throws:
PortalException

addOrUpdate

protected void addOrUpdate(T bean,
                           ITransaction transaction)
                    throws PortalException
Throws:
PortalException

delete

protected boolean delete(ID id,
                         ITransaction transaction)
                  throws PortalException
Deletes the bean with the given id from persistence.

Parameters:
id - the bean's id.
transaction - the transaction for persistence access. Must be a ITransactionHibernate.
Returns:
true if the bean was deleted, or false if it did not exist
Throws:
PortalException

evict

protected void evict(ID id,
                     ITransaction transaction)
              throws PortalException
Evicts the bean with the given id from the second-level cache.

Parameters:
id - the bean identifier.
transaction - the transaction for persistence access.
Throws:
PortalException
Since:
4.0.11

setReadOnly

protected void setReadOnly(ITransaction transaction,
                           Collection<T> beans)
                    throws DaoException
Sets a collection of beans to read-only state.

Throws:
DaoException

findByCriteria

                          throws DaoException
Convenience method for subclasses. All returned entities are returned in read-only state.

Throws:
DaoException
