public interface ResultObjectProvider
Interface that allows lazy/custom instantiation of input objects.
ResultList objects do not necessarily load in data all
at once. Instead, they may lazily load objects as necessary. So,
the lifespan of a ResultObjectProvider instance is
related to how the application deals with processing the
ResultList created with a given
ResultObjectProvider instance.
