Class SortingAtomicReader

An AtomicReader which supports sorting documents by a given Sort. You can use this class to sort an index as follows:

IndexWriter writer; // writer to which the sorted index will be added
DirectoryReader reader; // reader on the input index
Sort sort; // determines how the documents are sorted
AtomicReader sortingReader = SortingAtomicReader.Wrap(SlowCompositeReaderWrapper.Wrap(reader), sort);
writer.AddIndexes(reader);
reader.Dispose(); // alternatively, you can use a using block
writer.Dispose(); // alternatively, you can use a using block
