  Enclosing class:
    OfflineSorter

      public static class OfflineSorter.ByteSequencesWriter
      extends Object
      implements Closeable

  Utility class to emit length-prefixed byte[] entries to an output stream for sorting. Complementary to `OfflineSorter.ByteSequencesReader`. You must use `CodecUtil.writeFooter(org.apache.lucene.store.IndexOutput)` to write a footer at the end of the input file.

    - #### ByteSequencesWriter

          public ByteSequencesWriter(IndexOutput out)

      Constructs a ByteSequencesWriter to the provided DataOutput

  - ### Method Detail

    - #### write

          public final void write(BytesRef ref)
                           throws IOException

      Writes a BytesRef.
      Throws:
        `IOException`
      See Also:
        `write(byte[], int, int)`

    - #### write

          public final void write(byte[] bytes)
                           throws IOException

      Writes a byte array.
      Throws:
        `IOException`

        `write(byte[], int, int)`

    - #### write

          public void write(byte[] bytes,
                            int off,
