visit
Description copied from interface:PointValues.IntersectVisitor
Called for all documents in a leaf cell that's fully contained by the query. The consumer should blindly accept the docID.- Specified by:
visit
in interfacePointValues.IntersectVisitor
- Throws:
IOException
-
visit
Description copied from interface:PointValues.IntersectVisitor
Called for all documents in a leaf cell that crosses the query. The consumer should scrutinize the packedValue to decide whether to accept it. In the 1D case, values are visited in increasing order, and in the case of ties, in increasing docID order.- Specified by:
visit
in interfacePointValues.IntersectVisitor
- Throws:
IOException
-
