所有已实现的接口:

Serializable, ResultTransformer, TupleSubsetResultTransformer

public class AliasToBeanResultTransformer
extends AliasedTupleSubsetResultTransformer

Result transformer that allows to transform a result to a user specified class which will be populated via setter methods or fields matching the alias names.

 List resultWithAliasedBean = s.createCriteria(Enrolment.class)
                        .createAlias("student", "st")
                        .createAlias("course", "co")
                        .setProjection( Projections.projectionList()
                                        .add( Projections.property("co.description"), "courseDescription" )
                        )
                        .setResultTransformer( new AliasToBeanResultTransformer(StudentDTO.class) )
                        .list();
 

  StudentDTO dto = (StudentDTO)resultWithAliasedBean.get(0);

AliasToBeanResultTransformer

public AliasToBeanResultTransformer(Class resultClass)

方法详细资料

isTransformedValueATupleElement

public boolean isTransformedValueATupleElement(String[] aliases,
                                               int tupleLength)

从接口复制的说明: TupleSubsetResultTransformer

When a tuple is transformed, is the result a single element of the tuple?

参数:

aliases - - the aliases that correspond to the tuple

tupleLength - - the number of elements in the tuple

返回:

true, if the transformed value is a single element of the tuple; false, otherwise.

transformTuple

public Object transformTuple(Object[] tuple,
                             String[] aliases)

从接口复制的说明: ResultTransformer

Tuples are the elements making up each "row" of the query result. The contract here is to transform these elements into the final row.

指定者:

transformTuple 在接口中 ResultTransformer

覆盖:

transformTuple 在类中 BasicTransformerAdapter

参数:

tuple - The result elements

aliases - The result aliases ("parallel" array to tuple)

返回:

The transformed row.

equals

public boolean equals(Object o)

覆盖:

equals 在类中 Object

hashCode

public int hashCode()

覆盖:

hashCode 在类中 Object
