方法详细资料

excludeEmpty

protected abstract boolean excludeEmpty()

Should empty rows be excluded?

返回:

true Indicates the expression should 'exists'; false indicates 'not exists'

toSqlString

public final String toSqlString(Criteria criteria,
                                CriteriaQuery criteriaQuery)
                         throws HibernateException

Render the SQL fragment

指定者:

toSqlString 在接口中 Criterion

参数:

criteria - The local criteria

criteriaQuery - The overall criteria query

返回:

The generated SQL fragment

抛出:

HibernateException - Problem during rendering.

getQueryableCollection

protected QueryableCollection getQueryableCollection(String entityName,
                                                     String propertyName,
                                                     SessionFactoryImplementor factory)
                                              throws HibernateException

抛出:

HibernateException

getTypedValues

public final TypedValue[] getTypedValues(Criteria criteria,
                                         CriteriaQuery criteriaQuery)
                                  throws HibernateException

从接口复制的说明: Criterion

Return typed values for all parameters in the rendered SQL fragment

指定者:

getTypedValues 在接口中 Criterion

参数:

criteria - The local criteria

criteriaQuery - The overall criteria query

返回:

The types values (for binding)

抛出:

HibernateException - Problem determining types.

toString

public final String toString()

覆盖:

toString 在类中 Object
