public AliasToBeanConstructorResultTransformer(Constructor<T> constructor)

Instantiates a AliasToBeanConstructorResultTransformer.

Parameters
constructor:Constructor<T>

The contructor in which to wrap the tuples.

Method Detail

equalsback to summary
public boolean equals(Object other)

Overrides java.lang.Object.equals.

2 AliasToBeanConstructorResultTransformer are considered equal if they have the same defined constructor.

Parameters
other:Object

The other instance to check for equality.

Returns:boolean

True if both have the same defined constuctor; false otherwise.

hashCodeback to summary
public int hashCode()

Overrides java.lang.Object.hashCode.

Define our hashCode by our defined constructor's hasCode.

Returns:int

public List<E> transformList(List<E> collection)

Implements org.hibernate.transform.ResultTransformer.transformList.

Doc from org.hibernate.transform.ResultTransformer.transformList.

Here we have an opportunity to perform transformation on the query result as a whole. This might be useful to convert from one collection type to another or to remove duplicates from the result, etc.

Parameters
collection:List<E>

The result.

Returns:List<E>

The transformed result.

transformTupleback to summary
public Object transformTuple(Object[] tuple, String[] aliases)

Implements org.hibernate.transform.ResultTransformer.transformTuple.

Wrap the incoming tuples in a call to our configured constructor.

Parameters
tuple:Object[]

Doc from org.hibernate.transform.ResultTransformer.transformTuple.

The result elements

aliases:String[]

Doc from org.hibernate.transform.ResultTransformer.transformTuple.

The result aliases ("parallel" array to tuple)

Returns:Object

Doc from org.hibernate.transform.ResultTransformer.transformTuple.

The transformed row.
