Lucene.Net
3.0.3
Lucene.Net is a port of the Lucene search engine library, written in C# and targeted at .NET runtime users.
|
A Scorer for queries with a required subscorer and an excluding (prohibited) sub DocIdSetIterator.
This Scorer
implements DocIdSetIterator.Advance(int), and it uses the skipTo() on the given scorers.

Public Member Functions | |
ReqExclScorer (Scorer reqScorer, DocIdSetIterator exclDisi) | |
Construct a ReqExclScorer . | |
override int | NextDoc () |
Advances to the next document in the set and returns the doc it is currently on, or NO_MORE_DOCS if there are no more docs in the set. | |
override int | DocID () |
Returns the following:
| |
override float | Score () |
Returns the score of the current document matching the query. Initially invalid, until NextDoc() is called the first time. | |
override int | Advance (int target) |
Advances to the first beyond the current whose document number is greater than or equal to target. Returns the current document number or NO_MORE_DOCS if there are no more docs in the set. Behaves as if written: | |
Public Member Functions inherited from Lucene.Net.Search.Scorer | |
virtual void | Score (Collector collector) |
Scores and collects all matching documents. | |
virtual bool | Score (Collector collector, int max, int firstDocID) |
Expert: Collects matching documents in a range. Hook for optimization. Note, firstDocID is added to ensure that DocIdSetIterator.NextDoc() was called before this method. | |
Additional Inherited Members | |
Static Public Attributes inherited from Lucene.Net.Search.DocIdSetIterator | |
static readonly int | NO_MORE_DOCS = System.Int32.MaxValue |
When returned by NextDoc(), Advance(int) and DocID() it means there are no more docs in the iterator. | |

Advances to the first beyond the current whose document number is greater than or equal to target. Returns the current document number or NO_MORE_DOCS if there are no more docs in the set. Behaves as if written:
int advance(int target) { int doc; while ((doc = nextDoc()) < target) { } return doc; }
Some implementations are considerably more efficient than that.
NOTE: certain implemenations may return a different value (each time) if called several times in a row with the same target.
NOTE: this method may be called with NO_MORE_DOCS for efficiency by some Scorers. If your implementation cannot efficiently determine that it should exhaust, it is recommended that you check for that value in each call to this method.
NOTE: after the iterator has exhausted you should not call this method, as it may result in unpredicted behavior.
