determineRowTransformer

protected static <T> RowTransformer<T> determineRowTransformer(SqmSelectStatement<?> sqm,
 Class<T> resultClass,
 TupleMetadata tupleMetadata,
 QueryOptions queryOptions)

If the result type of the query is Tuple, Map, List, or any record or class type with an appropriate constructor, then we attempt to repackage the result tuple as an instance of the result type using an appropriate RowTransformer.

Parameters:

resultClass - The requested result type of the query

Returns:

A RowTransformer responsible for repackaging the result type
