Class IteratorSearchResponse

java.lang.Object
  org.apache.maven.index.AbstractSearchResponse
      org.apache.maven.index.IteratorSearchResponse

All Implemented Interfaces:

Closeable, Iterable<ArtifactInfo>

public class IteratorSearchResponse
extends AbstractSearchResponse
implements Iterable<ArtifactInfo>, Closeable

A Search Response for the "iterator-like" search request. The totalHitsCount reports total hits found on index, even if the set of ArtifactInfos are usually limited! On the flipside, the hitsCount is actually unknown, since this instance performs filtering on the fly, hence it does not know how many hits it will return ahead of time.
