hey,
you don't need to set the indexreader in the constructor. An
AtomicReader is passed in for each segment to
Collector#setNextReader(AtomicReaderContext)
If you want to use a given collector and extend it with some custom
code in collect I would likely write a delegate Collector like this:
public class DelegatingCollector extends Collector {
private final Collector delegate;
public DelegatingCollector(Collector delegate) {
this.delegate = delegate;
}
public Collector getDelegate() {
return delegate;
}
@Override
public void setScorer(Scorer scorer) throws IOException {
delegate.setScorer(scorer);
}
@Override
public void collect(int doc) throws IOException {
// ADD YOUR CUSTOM LOGIC HERE
delegate.collect(doc);
}
@Override
public void setNextReader(AtomicReaderContext context) throws IOException {
// THIS IS WHERE YOU GET THE READER --> context.reader()
delegate.setNextReader(context);
}
@Override
public boolean acceptsDocsOutOfOrder() {
return delegate.acceptsDocsOutOfOrder();
}
}
maybe this is easier for you? then you can simply call
TopScoreDocCollector.create(int numHits, boolean docsScoredInOrder);
and use the specialized collector for your settings in the delegate?
