- Enclosing class:
OffHeapFloatVectorValues
public static class OffHeapFloatVectorValues.DenseOffHeapVectorValues
extends OffHeapFloatVectorValues
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 classFloatVectorValues- Throws:
IOException
-
ordToDoc
public int ordToDoc(int ord) Description copied from class:KnnVectorValuesReturn the docid of the document indexed with the given vector ordinal. This default implementation returns the argument and is appropriate for dense values implementations where every doc has a single value.- Overrides:
ordToDocin classKnnVectorValues
-
getAcceptOrds
Description copied from class:KnnVectorValuesReturns a Bits accepting docs accepted by the argument and having a vector value- Overrides:
getAcceptOrdsin classKnnVectorValues
-
iterator
Description copied from class:KnnVectorValuesCreate an iterator for this instance.- Overrides:
iteratorin classKnnVectorValues
-
scorer
Description copied from class:FloatVectorValuesReturn aVectorScorerfor the given query vector and the currentFloatVectorValues.- Overrides:
scorerin classFloatVectorValues- Parameters:
query- the query vector- Returns:
- a
VectorScorerinstance or null - Throws:
IOException
