I - The type of the IDs by which the entities are stored in the index.T - The type of the entities that are stored in the index.public class IndexedQuery<I,T> extends Predicate<T> implements DataSource<T>, Paginated<T>
IndexPredicate together with a DataSource that returns
matching results from the index.
Appropriate to return as the rootmost predicate that can be processed using the secondary
index; such predicates must also implement DataSource to be chosen by the query
processor.
