dimension
public int dimension()Description copied from class:KnnVectorValues
Return the dimension of the vectors- Specified by:
dimension
in classKnnVectorValues
-
size
public int size()Description copied from class:KnnVectorValues
Return the number of vectors for this field.- Specified by:
size
in classKnnVectorValues
- Returns:
- the number of vectors returned by this iterator
-
vectorValue
public float[] vectorValue(int ord) Description copied from class:FloatVectorValues
Return the vector value for the given vector ordinal which must be in [0, size() - 1], otherwise IndexOutOfBoundsException is thrown. The returned array may be shared across calls.- Specified by:
vectorValue
in classFloatVectorValues
- Returns:
- the vector value
-
iterator
Description copied from class:KnnVectorValues
Create an iterator for this instance.- Overrides:
iterator
in classKnnVectorValues
-
scorer
Description copied from class:FloatVectorValues
Return aVectorScorer
for the given query vector and the currentFloatVectorValues
.- Overrides:
scorer
in classFloatVectorValues
- Parameters:
query
- the query vector- Returns:
- a
VectorScorer
instance or null
-
copy
Description copied from class:KnnVectorValues
Creates 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:
copy
in classFloatVectorValues
