Constructor Detail

HibernateFactoryAndRepository

public HibernateFactoryAndRepository()

Method Detail

createCriteria

protected org.hibernate.Criteria createCriteria(java.lang.Class<?> cls)

Create a Hibernate Criteria for the class persisted by this repository

createQuery

protected org.hibernate.Query createQuery(java.lang.String query)

Create a Hibernate Query using a complete query string. This can be used to query any entity.

getNamedQuery

protected org.hibernate.Query getNamedQuery(java.lang.String name)

Return a named Hibernate Query which is defined in hibernate.cfg.xml.

Parameters:

name - the Query name

createCountQuery

protected org.hibernate.Query createCountQuery(java.lang.String whereClause,
                                               java.lang.Class<?> cls)

A shortcut for creating a count(*) Query on the class for this repository. The query generated is

 select count(*) from <cls> as o {where <whereClause>}
 

The whereClause is optional.

To generate more complex queries, possibly using other classes, use the createQuery(String)} method

Parameters:

whereClause - the where clause, not including "where", or null to count all instances.

createEntityQuery

protected org.hibernate.Query createEntityQuery(java.lang.String whereClause,
                                                java.lang.Class<?> cls)

A shortcut for creating a Query on the class for this repository. The query generated is

 from <cls> as o where <whereClause>
 

The whereClause must be specified, to select all instances use #allInstances().

To generate more complex queries, possibly using other classes, use createQuery(String)}.

Parameters:

whereClause - the where clause, not including "where"

findByCriteria

protected java.util.List<?> findByCriteria(org.hibernate.Criteria criteria,
                                           java.lang.Class<?> cls)

findUniqueResultByCriteria

protected java.lang.Object findUniqueResultByCriteria(org.hibernate.Criteria criteria,
                                                      java.lang.Class<?> cls)

findUniqueResultByQuery

protected java.lang.Object findUniqueResultByQuery(org.hibernate.Query query,
                                                   java.lang.Class<?> cls)

findFirstByCriteria

protected java.lang.Object findFirstByCriteria(org.hibernate.Criteria criteria,
                                               java.lang.Class<?> cls)

findByQuery

protected java.util.List<?> findByQuery(org.hibernate.Query query,
                                        java.lang.Class<?> cls)

findFirstByQuery

protected java.lang.Object findFirstByQuery(org.hibernate.Query query,
                                            java.lang.Class<?> cls)

findByQuery

protected java.util.List<?> findByQuery(java.lang.String query,
                                        java.lang.Class<?> cls)

findFirstByQuery

protected java.lang.Object findFirstByQuery(java.lang.String query,
                                            java.lang.Class<?> cls)

getFirst

protected java.lang.Object getFirst(java.util.List<?> list)

Return the first object in a list. If the array is null, or is empty, then return null.

countNotZero

protected boolean countNotZero(org.hibernate.Query query)

Return true if the Query returns an integer > 0. The Query MUST return a single value, which must be an integer, e.g. "select count(*) from myClass". This is a utility method to help with common repository usage.

findByCriteria

protected java.util.List<?> findByCriteria(HibernateInstancesCriteria criteria,
                                           java.lang.Class<?> cls)
