类 AliasToEntityMapResultTransformer

java.lang.Object

org.hibernate.transform.BasicTransformerAdapter

org.hibernate.transform.AliasedTupleSubsetResultTransformer

org.hibernate.transform.AliasToEntityMapResultTransformer

所有已实现的接口:

Serializable, ResultTransformer, TupleSubsetResultTransformer

public class AliasToEntityMapResultTransformer
extends AliasedTupleSubsetResultTransformer

ResultTransformer implementation which builds a map for each "row", made up of each aliased value where the alias is the map key.

Since this transformer is stateless, all instances would be considered equal. So for optimization purposes we limit it to a single, singleton instance.

方法详细资料

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.

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.
