Examples of FixedBitSet

org.apache.lucene.util.FixedBitSet
BitSet of fixed length (numBits), backed by accessible ( {@link #getBits}) long[], accessed with an int index, implementing Bits and DocIdSet. Unlike {@link OpenBitSet} this bit set does not auto-expand, cannothandle long index, and does not have fastXX/XX variants (just X). @lucene.internal
