Constructor	Description
PointInShapeIntersectVisitor(DocIdSetBuilder hits, GeoShape shape, XYZBounds bounds)

Method Summary

Modifier and Type	Method	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	grow(int count)	Notifies the caller that this many documents are about to be visited
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.
void	visit(DocIdSetIterator iterator)	Similar to PointValues.IntersectVisitor.visit(int), but a bulk visit and implementations may have their optimizations.

Constructor Details

PointInShapeIntersectVisitor

public PointInShapeIntersectVisitor(DocIdSetBuilder hits,
 GeoShape shape,
 XYZBounds bounds)

Method Details

grow

public void grow(int count)

Description copied from interface: PointValues.IntersectVisitor

Notifies the caller that this many documents are about to be visited

Specified by:

grow in interface PointValues.IntersectVisitor

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(DocIdSetIterator iterator)
           throws IOException

Description copied from interface: PointValues.IntersectVisitor

Similar to PointValues.IntersectVisitor.visit(int), but a bulk visit and implementations may have their optimizations.

Specified by:

visit in interface PointValues.IntersectVisitor

Throws:

IOException

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
