Class HibernateRepository<E,I extends Serializable>

java.lang.Object

net.sf.r4h.HibernateRepository<E,I>

Type Parameters:

E - a type of entity

I - a type of identity key

public class HibernateRepository<E,I extends Serializable>
extends Object

/** The goal of this class is to provide API that allows to write common CRUD operations in ONE line of code. In addition to it's methods it provides paging, improved ordering (see Order) and restriction (see Restrictions) In methods with paging pages numbers start from 1. By default Restriction is Restrictions#EQUAL

saveOrUpdate

public E saveOrUpdate(E entity)

saveOrUpdateAndFlush

public E saveOrUpdateAndFlush(E entity)

Saves or updates entity and flushes session, this allows to use saved entity id

Parameters:

entity -

Returns:

saves entity

save

public E save(E entity)

saveAndFlush

public E saveAndFlush(E entity)

Saves entity and flushes session, this allows to use saved entity id

Parameters:

entity -

Returns:

saves entity

merge

public E merge(E entity)

delete

public E delete(E entity)

delete

public E delete(Serializable id)

deleteAll

public int deleteAll(String entityName)

Deletes all entities of given entityName

Parameters:

entityName -

Returns:

number of deleted entities

deleteAll

public int deleteAll()

Deletes all entities of given entityClass

Returns:

number of deleted entities

deleteAllPreFetched

public List<E> deleteAllPreFetched()

First fetches all entities and than deletes it one by one. Is needed to correctly delete graphs of objects since it deletes references and unlike deleteAll() avoids constraint violation WARNING: This method is useful in tests, but seldom needed on production since it is very inefficient.

Returns:

execute

protected <T> T execute(net.sf.r4h.HibernateRepository.CriteriaHibernateCallback<?> criteriaHibernateCallback)
