visit
public void visit(int docID) throws java.io.IOException
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:
java.io.IOException
-
visit
public void visit(int docID, byte[] packedValue) throws java.io.IOException
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:
java.io.IOException
-
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 interfacePointValues.IntersectVisitor
-
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:
