constructor(state: SegmentWriteState, confidenceInterval: Float?, rawVectorDelegate: FlatVectorsWriter, scorer: FlatVectorsScorer)

Types

object Companion

Properties

open val childResources: MutableCollection<Accountable>

Returns nested resources of this class. The result should be a point-in-time snapshot (to avoid race conditions).

val vectorScorer: FlatVectorsScorer

Scorer for flat vectors

Functions

open override fun addField(fieldInfo: FieldInfo): FlatFieldVectorsWriter<*>

Add a new field for indexing

open override fun close()

open override fun finish()

Called once at the end before close

open override fun flush(maxDoc: Int, sortMap: Sorter.DocMap?)

Flush all buffered data on disk *

getFlatVectorScorer

fun getFlatVectorScorer(): FlatVectorsScorer

fun merge(mergeState: MergeState)

Merges the segment vectors for all fields. This default implementation delegates to .mergeOneField, passing a KnnVectorsReader that combines the vector values and ignores deleted documents.

open override fun mergeOneField(fieldInfo: FieldInfo, mergeState: MergeState)

Write field for merging

mergeOneFieldToIndex

open override fun mergeOneFieldToIndex(fieldInfo: FieldInfo, mergeState: MergeState): CloseableRandomVectorScorerSupplier

Write the field for merging, providing a scorer over the newly merged flat vectors. This way any additional merging logic can be implemented by the user of this class.

open override fun ramBytesUsed(): Long

Return the memory usage of this object in bytes. Negative values are illegal.
