 int maxDoc,
 PointValues values)
                    throws IOException

Sole constructor

Throws:

IOException

Method Details

getPointCountSeen

public long getPointCountSeen()

Returns total number of points in this BKD tree

getDocCountSeen

public long getDocCountSeen()

Returns total number of unique docIDs in this BKD tree

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:

compare in interface PointValues.IntersectVisitor

checkPackedValue

private void checkPackedValue(String desc,
 byte[] packedValue,
 int docID)
