org.apache.lucene.search.PointInSetQuery.SinglePointVisitor
- All Implemented Interfaces:
PointValues.IntersectVisitor
- Enclosing class:
PointInSetQuery
private class PointInSetQuery.SinglePointVisitor
extends Object
implements PointValues.IntersectVisitor
IntersectVisitor that queries against a highly degenerate shape: a single point. This is used
in the > 1D case.

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 interfacePointValues.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 interfacePointValues.IntersectVisitor
-
visit
Description copied from interface:PointValues.IntersectVisitor
Similar toPointValues.IntersectVisitor.visit(int)
, but a bulk visit and implementations may have their optimizations.- Specified by:
visit
in interfacePointValues.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 interfacePointValues.IntersectVisitor
-
visit
Description copied from interface:PointValues.IntersectVisitor
Similar toPointValues.IntersectVisitor.visit(int, byte[])
but in this case the packedValue can have more than one docID associated to it. The provided iterator should not escape the scope of this method so that implementations of PointValues are free to reuse it,- Specified by:
visit
in interfacePointValues.IntersectVisitor
- Throws:
IOException
-
compare
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:
