public class TupleConverter<T> extends Object implements org.springframework.core.convert.converter.Converter<jakarta.persistence.Tuple,T>
Converts JPA Tuple results into DTO instances by invoking a matching constructor discovered for the target DTO type.

Constructor selection is delegated to the supplied PreferredConstructorDiscoverer. Once a matching constructor has been found for the first tuple shape seen by this converter, that constructor is cached on the converter instance for subsequent conversions.
