SUMMARY: INNER | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
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.
