org.apache.lucene.backward_codecs.lucene90.Lucene90PostingsFormat.IntBlockTermState
- All Implemented Interfaces:
Cloneable
- Enclosing class:
Lucene90PostingsFormat
Holds all state required for
Lucene90PostingsReader
to produce a PostingsEnum
without re-seeking the terms dict.- NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.

lastPosBlockOffset
public long lastPosBlockOffsetfile offset for the last position in the last block, if there are more thanForUtil.BLOCK_SIZE
positions; otherwise -1One might think to use total term frequency to track how many positions are left to read as we decode the blocks, and decode the last block differently when num_left_positions < BLOCK_SIZE. Unfortunately this won't work since the tracking will be messed up when we skip blocks as the skipper will only tell us new position offset (start of block) and number of positions to skip for that block, without telling us how many positions it has skipped.
