Method Details

writeField

public void writeField(FieldInfo fieldInfo,
 KnnVectorsReader knnVectorsReader)
                throws IOException

Description copied from class: KnnVectorsWriter

Write all values contained in the provided reader

Specified by:

writeField in class KnnVectorsWriter

Throws:

IOException

merge

public final void merge(MergeState mergeState)
                 throws IOException

Description copied from class: KnnVectorsWriter

Merges the segment vectors for all fields. This default implementation delegates to KnnVectorsWriter.writeField(org.apache.lucene.index.FieldInfo, org.apache.lucene.codecs.KnnVectorsReader), passing a KnnVectorsReader that combines the vector values and ignores deleted documents.

Overrides:

merge in class KnnVectorsWriter

Throws:

IOException

finish

public void finish()
            throws IOException

Description copied from class: KnnVectorsWriter

Called once at the end before close

Specified by:

finish in class KnnVectorsWriter

Throws:

IOException

close

public void close()
           throws IOException

Throws:

IOException

getInstance

private KnnVectorsWriter getInstance(FieldInfo field)
                              throws IOException

Throws:

IOException
