Method Summary

Modifier and Type	Method and Description
PointValues.Relation	compare(byte[] minPackedValue, byte[] maxPackedValue) Called for non-leaf cells to test how the cell relates to the query, to determine how to further recurse down the tree.
void	visit(int docID) Called for all documents in a leaf cell that's fully contained by the query.
void	visit(int docID, byte[] packedValue) Called for all documents in a leaf cell that crosses the query.

VerifyVisitor

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 interface PointValues.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 interface PointValues.IntersectVisitor

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:
