Class AbstractCriteriaBuilder<QB extends QueryBuilderBase<QB,QW>,QT,QW>

java.lang.Object

ch.tocco.nice2.persist.core.impl.hibernate.query.QueryBuilderBaseImpl<QB,QW>

ch.tocco.nice2.persist.core.impl.hibernate.query.AbstractCriteriaBuilder<QB,QT,QW>

Type Parameters:

QB - Type of the actual AbstractCriteriaBuilder implementation so that it can be returned from the builder methods

QT - Return type of the CriteriaQuery query

QW - Type that should be returned from the QueryBuilderBaseImpl.build() method

All Implemented Interfaces:

QueryBuilderBase<QB,QW>

Direct Known Subclasses:

CriteriaCountQueryBuilder, CriteriaDeleteBuilderImpl, CriteriaQueryBuilderImpl

public abstract class AbstractCriteriaBuilder<QB extends QueryBuilderBase<QB,QW>,QT,QW>
extends QueryBuilderBaseImpl<QB,QW>

An abstract base class for query builders that are based on a CriteriaQuery.
