All Implemented Interfaces:
  `HasIndexSlice`

Enclosing class:
  `OffHeapByteVectorValues`

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

  - ### copy

    public OffHeapByteVectorValues.DenseOffHeapVectorValues copy() throws IOException
    Description copied from class: `KnnVectorValues`
    Creates a new copy of this `KnnVectorValues`. This is helpful when you need to access different values at once, to avoid overwriting the underlying vector returned.
    Specified by:
      `copy` in class `ByteVectorValues`
    Throws:
      `IOException`

  - ### iterator

    public KnnVectorValues.DocIndexIterator iterator()
    Description copied from class: `KnnVectorValues`
    Create an iterator for this instance.
    Overrides:
      `iterator` in class `KnnVectorValues`

  - ### getAcceptOrds

    public Bits getAcceptOrds(Bits acceptDocs)
    Description copied from class: `KnnVectorValues`
    Returns a Bits accepting docs accepted by the argument and having a vector value
    Overrides:
      `getAcceptOrds` in class `KnnVectorValues`

  - ### scorer

    public VectorScorer scorer(byte[] query) throws IOException
    Description copied from class: `ByteVectorValues`
    Return a `VectorScorer` for the given query vector.
    Overrides:
      `scorer` in class `ByteVectorValues`
    Parameters:
      `query` - the query vector
    Returns:
      a `VectorScorer` instance or null
    Throws:
      `IOException`
