transformTuple

public Object transformTuple(Object[] tuple,
                             String[] aliases)
Wrap the incoming tuples in a call to our configured constructor.

transformTuple in interface ResultTransformer
Parameters:
tuple - The result elements
aliases - The result aliases ("parallel" array to tuple)
Returns:
The transformed row.

transformList

public List transformList(List collection)
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.

Specified by:
transformList in interface ResultTransformer
Parameters:
collection - The result.
Returns:
The transformed result.

hashCode

public int hashCode()
Define our hashCode by our defined constructor's hasCode.

Overrides:
hashCode in class Object
Returns:
Our defined ctor hashCode

equals

public boolean equals(Object other)
2 AliasToBeanConstructorResultTransformer are considered equal if they have the same defined constructor.

Overrides:
equals in class Object
Parameters:
other - The other instance to check for equality.
Returns:
True if both have the same defined constuctor; false otherwise.
