public interface Filter<C extends Enum<C>>

Interface for components that filter/categorize rows. A filter will process incoming rows and label them with a category. A category is defined as a value in an enum. When a row is categorized, this category can then be used to set up a requirement for succeeding row processing. A sub-interface of Filter exists, QueryOptimizedFilter, which allows filter functionality to be pushed down to the query in certain circumstances where it is desirable to do so.
