public class Siren10SkipListReader
extends org.apache.lucene.codecs.MultiLevelSkipListReader

Implementation of the MultiLevelSkipListReader for the default block-based posting list format of SIREn 1.0.

The MultiLevelSkipListReader implementation is based on document count, but it is used here with block count instead of document count. In order to make it compatible with block, this class is converting document count into block count and vice versa.
