AliasToEntityMapResultTransformer (Hibernate JavaDocs)

java.lang.Object
- org.hibernate.transform.BasicTransformerAdapter
- - org.hibernate.transform.AliasedTupleSubsetResultTransformer
  - - org.hibernate.transform.AliasToEntityMapResultTransformer

All Implemented Interfaces:

java.io.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.

public java.lang.Object transformTuple(java.lang.Object[] tuple,
                                       java.lang.String[] aliases)
```
    Description copied from interface: 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.
    
    Specified by:
    
    transformTuple in interface ResultTransformer
    
    Overrides:
    
    transformTuple in class BasicTransformerAdapter
    
    Parameters:
    
    tuple - The result elements
    
    aliases - The result aliases ("parallel" array to tuple)
    
    Returns:
    
    The transformed row.
  - isTransformedValueATupleElement
```
public boolean isTransformedValueATupleElement(java.lang.String[] aliases,
                                               int tupleLength)
```
    Description copied from interface: TupleSubsetResultTransformer
    
    When a tuple is transformed, is the result a single element of the tuple?
    
    Parameters:
    
    aliases - - the aliases that correspond to the tuple
    
    tupleLength - - the number of elements in the tuple
    
    Returns:
    
    true, if the transformed value is a single element of the tuple; false, otherwise.
