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.

Method Details
-
copy
Description copied from class:KnnVectorValuesCreates a new copy of thisKnnVectorValues. This is helpful when you need to access different values at once, to avoid overwriting the underlying vector returned.- Specified by:
copyin classByteVectorValues- Throws:
IOException
-
iterator
Description copied from class:KnnVectorValuesCreate an iterator for this instance.- Overrides:
iteratorin classKnnVectorValues
-
getAcceptOrds
Description copied from class:KnnVectorValuesReturns a Bits accepting docs accepted by the argument and having a vector value- Overrides:
getAcceptOrdsin classKnnVectorValues
-
scorer
Description copied from class:ByteVectorValuesReturn aVectorScorerfor the given query vector.- Overrides:
scorerin classByteVectorValues- Parameters:
query- the query vector- Returns:
- a
VectorScorerinstance or null - Throws:
IOException
