ObjectFilter Interface
- public interface ObjectFilter
This interface is used to filter objects.
The caller passes an implementing class to a method and
receives callbacks that allow the caller to filter the output objects
as desired. Filters can either build up state within themselves or can
merely block or pass objects based on a filtering algorithm.
