- *
- * The rank structure for DENSE blocks is an array of unsigned {@code short}s with an entry

- * Each rank-entry states the number of set bits within the block up to the bit before the

- *
- * See https://en.wikipedia.org/wiki/Succinct_data_structure for details on rank structures.
- * The alternative to using the rank structure is iteration and summing of set bits for all
- * entries in the DENSE sub-block up until the wanted bit, with a worst-case of 1024 entries.
- * The rank cache overhead for a single DENSE block is 128 shorts (128*16 = 2048 bits) or

- * Wrapper for OpenBitSet which creates and exposes a rank cache. The rank-cache scales to 2 billion bits.
- *
- * The rankCache has a long for every 2048 bits and thus has an overhead of 3.17% relative to the given bit set.
- * Performance is O(1):
- * 1 lookup in cache,
- * a maximum of 3 sums,
- * a maximum of 8 Long.bitCounts.
- *
- * Creation performance is equivalent to a full count of all set bits in the bit set O(n).
- *
- * Note: {@link #buildRankCache()} must be called once after the bit set has been created or changed and before
- * calling {@link #rank(long)}.
- *
- * The design is based heavily on the article
- * Space-Efficient, High-Performance Rank and Select Structures on Uncompressed Bit Sequences
- * by Dong Zhou, David G. Andersen, Michael Kaminsky, Carnegie Mellon University, Intel Labs
- * http://www.cs.cmu.edu/~dga/papers/zhou-sea2013.pdf

-/**
- * Caching of IndexedDISI with two strategies:
- *
- * A lookup table for block blockCache and index.
- *
- * The lookup table is an array of {@code long}s with an entry for each block. It allows for
- * direct jumping to the block, as opposed to iteration from the current position and forward
- * one block at a time.
- *
- * Each long entry consists of 2 logical parts:
- *
- * The first 31 bits holds the index (number of set bits in the blocks) up to just before the
- * wanted block. The next 33 bits holds the offset into the underlying slice.
- * As there is a maximum of 2^16 blocks, it follows that the maximum size of any block must
- * not exceed 2^17 bits to avoid overflow. This is currently the case, with the largest
- * block being DENSE and using 2^16 + 32 bits, and is likely to continue to hold as using
- * more than double the amount of bits is unlikely to be an efficient representation.
- * The cache overhead is numDocs/1024 bytes.
- *
- * Note: There are 4 types of blocks: ALL, DENSE, SPARSE and non-existing (0 set bits).
- * In the case of non-existing blocks, the entry in the lookup table has index equal to the
- * previous entry and offset equal to the next non-empty block.
- *
- * The performance overhead for creating a cache instance is equivalent to visiting every 65536th
- * doc value for the given field, i.e. it scales lineary to field size.
