Mark Miller commented on LUCENE-1483:
-------------------------------------
Here is what that example policy has to be essentially. We just have to create
a good way to do the right conversion I guess. I'll work on whatever you don't
put up when you share your latest optimizations.
{code}
case SortField.STRING_ORD:
return new ComparatorPolicy(){
private FieldComparator comparator = new
FieldComparator.StringOrdComparator(numHits, field);
private boolean first = true;
private boolean second = true;
public FieldComparator nextComparator(FieldComparator oldComparator,
IndexReader reader, int numHits, int numSlotsFull)
throws IOException {
if(first) {
first = false;
return comparator;
} else if(second){
StringOrdValOnDemComparator comp = new
FieldComparator.StringOrdValOnDemComparator(numHits, field);
comp.values =
((FieldComparator.StringOrdComparator)comparator).values;
comp.ords = ((FieldComparator.StringOrdComparator)comparator).ords;
comp.currentReaderIndex = 1;
comparator = comp;
second = false;
return comp;
}
return comparator;
}};
{code}
