purgeCompact method

void purgeCompact(
  1. Set<TKey> keys
)

Intention-revealing non-contiguous compaction: clears the removed keys' reverse-index slots, sweeps the order, dropping keys AND any zombie entries whose nid was already released (the zombie protocol documented on removeWhereKeyIn), then rebuilds the reverse index wholesale. The full "non-contiguous removal" protocol in one owner.

Implementation

void purgeCompact(Set<TKey> keys) {
  // L25.8: no per-key `clearIndexOf` here; `rebuildIndex` opens with
  // `resetIndexAll`, which clears every slot before re-indexing.
  removeWhereKeyIn(keys);
  rebuildIndex();
}
