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
Description copied from class:ByteVectorValues
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 classByteVectorValues
- Returns:
- the vector value
- Throws:
IOException
-
ordToDoc
public int ordToDoc(int ord) Description copied from class:KnnVectorValues
Return 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:
ordToDoc
in classKnnVectorValues
-
iterator
Description copied from class:KnnVectorValues
Create an iterator for this instance.- Overrides:
