intersect
public void intersect(PointValues.IntersectVisitor visitor) throws java.io.IOException
Description copied from class:PointValues
Finds all documents and points matching the provided visitor. This method does not enforce live documents, so it's up to the caller to test whether each document is deleted, if necessary.- Specified by:
intersect
in classPointValues
- Throws:
java.io.IOException
-
estimatePointCount
public long estimatePointCount(PointValues.IntersectVisitor visitor)
Description copied from class:PointValues
Estimate the number of points that would be visited byPointValues.intersect(org.apache.lucene.index.PointValues.IntersectVisitor)
with the givenPointValues.IntersectVisitor
. This should run many times faster thanPointValues.intersect(IntersectVisitor)
.- Specified by:
