Constructor Detail

AliasToBeanConstructorResultTransformer

public AliasToBeanConstructorResultTransformer(java.lang.reflect.Constructor constructor)

Instantiates a AliasToBeanConstructorResultTransformer.

Parameters:

constructor - The contructor in which to wrap the tuples.

Method Detail

transformTuple

public java.lang.Object transformTuple(java.lang.Object[] tuple,
                              java.lang.String[] aliases)

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

Specified by:

transformTuple in interface ResultTransformer

Parameters:

tuple - The result elements

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

Returns:

The transformed row.

transformList

public java.util.List transformList(java.util.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 java.lang.Object

Returns:

Our defined ctor hashCode

equals

public boolean equals(java.lang.Object other)

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

Overrides:

equals in class java.lang.Object

Parameters:

other - The other instance to check for equality.

Returns:

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