Interface IHitCollector<V extends Comparable<V>>

Type Parameters:

V - The generic type of the document identifier.

All Known Implementing Classes:

MultiTokenHitCollector, SingleTokenHitCollector

public interface IHitCollector<V extends Comparable<V>>

Interface used to collect Hits from the ReadIndexTask. Switched over to this interface to allow for an optimization when only one token is presented for search - in this case we now use a simple array of hits rather than a heavyweight ConcurrentHashMap.
