示例1: getSeqNosSet
import org.apache.lucene.index.LeafReader; //导入方法依赖的package包/类
private static FixedBitSet getSeqNosSet(final IndexReader reader, final long highestSeqNo) throws IOException {
// _seq_no are stored as doc values for the time being, so this is how we get them
// (as opposed to using an IndexSearcher or IndexReader)
final FixedBitSet bitSet = new FixedBitSet((int) highestSeqNo + 1);
final List<LeafReaderContext> leaves = reader.leaves();
if (leaves.isEmpty()) {
return bitSet;
}
for (int i = 0; i < leaves.size(); i++) {
final LeafReader leaf = leaves.get(i).reader();
