Method Detail

checkAndThrowWithSampling

private void checkAndThrowWithSampling()

Throws ExitableDirectoryReader.ExitingReaderException if QueryTimeout.shouldExit() returns true, or if Thread.interrupted() returns true.

checkAndThrow

private void checkAndThrow()

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 interface PointValues.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 interface PointValues.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 interface PointValues.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:

grow in interface PointValues.IntersectVisitor
