Method NewAnonymous

NewAnonymous(Action<Scorer>, Action<Int32>, Action<AtomicReaderContext>, Func<Boolean>)

Creates a new instance with the ability to specify the body of the SetScorer(Scorer) method through the setScorer parameter, the body of the Collect(Int32) method through the collect parameter, the body of the SetNextReader(AtomicReaderContext) method through the setNextReader parameter, and the body of the AcceptsDocsOutOfOrder property through the acceptsDocsOutOfOrder parameter. Simple example:

    IndexSearcher searcher = new IndexSearcher(indexReader);
    OpenBitSet bits = new OpenBitSet(indexReader.MaxDoc);
    int docBase;
    searcher.Search(query, 
        Collector.NewAnonymous(setScorer: (scorer) =>
        {
            // ignore scorer
        }, collect: (doc) =>
        {
            bits.Set(doc + docBase);
        }, setNextReader: (context) =>
        {
            docBase = context.DocBase;
        }, acceptsDocsOutOfOrder: () =>
        {
            return true;
        })
    );
