  Modifier and Type
  Method
  Description

  Creates an ordinal map based on the provided sorted set doc values to merges
  `protected static BinaryDocValues`
  DocValuesConsumer.`getMergedBinaryDocValues(FieldInfo mergeFieldInfo, MergeState mergeState)`
  Returns a merged binary doc values instance from all producers in the provided merge state.
  `protected static NumericDocValues`
  DocValuesConsumer.`getMergedNumericDocValues(MergeState mergeState, FieldInfo mergeFieldInfo)`

  `final void`
  KnnVectorsWriter.`merge(MergeState mergeState)`
  Merges the segment vectors for all fields using a two-phase strategy: Phase 1: Merge flat vectors for all fields by calling `KnnVectorsWriter.mergeOneField(FieldInfo, MergeState)`, collecting deferred work (runnables) for each field.
  `void`
  NormsConsumer.`merge(MergeState mergeState)`
  Merges in the fields from the readers in `mergeState`.
  `void`
  PointsWriter.`merge(MergeState mergeState)`
  Default merge implementation to merge incoming points readers by visiting all their points and adding to this writer
  `int`
  StoredFieldsWriter.`merge(MergeState mergeState)`
  Merges in the stored fields from the readers in `mergeState`.
  `int`
  TermVectorsWriter.`merge(MergeState mergeState)`
  Merges in the term vectors from the readers in `mergeState`.
  `void`
  DocValuesConsumer.`mergeBinaryField(FieldInfo mergeFieldInfo, MergeState mergeState)`
  Merges the binary docvalues from `MergeState`.
  `static ByteVectorValues`
  KnnVectorsWriter.MergedVectorValues.`mergeByteVectorValues(FieldInfo fieldInfo, MergeState mergeState)`
  Returns a merged view over all the segment's `ByteVectorValues`.
  `static FloatVectorValues`
  KnnVectorsWriter.MergedVectorValues.`mergeFloatVectorValues(FieldInfo fieldInfo, MergeState mergeState)`
  Returns a merged view over all the segment's `FloatVectorValues`.

  BufferingKnnVectorsWriter.`mergeOneField(FieldInfo fieldInfo, MergeState mergeState)`
  `IORunnable`
  KnnVectorsWriter.`mergeOneField(FieldInfo fieldInfo, MergeState mergeState)`
  Merges vectors for a single field, returning a runnable for any deferred work (e.g., HNSW graph construction).
  `protected void`
  PointsWriter.`mergeOneField(MergeState mergeState, FieldInfo fieldInfo)`
  Default naive merge implementation for one field: it just re-indexes all the values from the incoming segment.
  `void`
