int |
docID()
Returns the doc ID that is currently being scored.
|
int |
freq()
Returns the freq of this Scorer on the current document
|
java.util.Collection<Scorer.ChildScorer> |
getChildren()
Returns child sub-scorers positioned on the current document
Note that this method should not be called on Scorers passed to
LeafCollector.setScorer(Scorer) ,
as these may be synthetic Scorers produced by BulkScorer which will throw an Exception. |

iterator()
Return a
DocIdSetIterator over matching documents. |
float |
score()
Returns the score of the current document matching the query.
|
private void |
validateParentDoc()
Detect mis-use, where provided parent query in fact
sometimes returns child documents.

over matching documents.
The returned iterator will either be positioned on -1
if no
documents have been scored yet, DocIdSetIterator.NO_MORE_DOCS
if all documents have been scored already, or the last document id that
has been scored otherwise.
The returned iterator is a view: calling this method several times will
return iterators that have the same state.private void validateParentDoc()
