All Implemented Interfaces:
  `HasIndexSlice`

Enclosing class:
  `OffHeapQuantizedByteVectorValues`

public static class OffHeapQuantizedByteVectorValues.DenseOffHeapVectorValues extends OffHeapQuantizedByteVectorValues
Dense vector values that are stored off-heap. This is the most common case when every doc has a vector.
