方法详细资料

getTypedValues

public 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.

toSqlString

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

从接口复制的说明: Criterion

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.

getNaturalIdValues

public Map<String,Object> getNaturalIdValues()

Get a map of set of the natural identifier values set on this criterion (for composite natural identifiers this need not be the full set of properties).

返回:

The value map.

set

public NaturalIdentifier set(String property,
                             Object value)

Set a natural identifier value for this expression

参数:

property - The specific property name

value - The value to use

返回:
