Method Detail

visit
public void visit(int docID)
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
-
visit
public void visit(int docID, byte[] packedValue)
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
-
updateBottomNearestDistance
private void updateBottomNearestDistance()

compare
public PointValues.Relation compare(byte[] minPackedValue, byte[] maxPackedValue)
Description copied from interface:PointValues.IntersectVisitor
Called for non-leaf cells to test how the cell relates to the query, to determine how to further recurse down the tree.- Specified by:
