Tim Smith commented on LUCENE-2276:
-----------------------------------
instead of doing the following everywhere:
{code}
final Document doc(int n, FieldSelector fieldSelector) throws
CorruptIndexException, IOException {
return doc(n, null, fieldSelector);
}
{code}
you could do:
{code}
final Document doc(int n, FieldSelector fieldSelector) throws
CorruptIndexException, IOException {
return doc(n, new Document(), fieldSelector);
}
{code}
then, the interface for doc(int, Document, FieldSelector) can state that the
document must not be null, and can skip the if null, new Document check later on
> Add IndexReader.document(int, Document, FieldSelector)
