从IntStream，Java 8返回LinkedHashMap

Question

我有此代码。

  private static Map<Long, List<TimePitchValue>> alternativeMethod(AudioFormat audioformat, 
      List<ChunkDTO> listChunkDTO, long index, int sizeChunk) {

    int numBytesPerSample = audioformat.getSampleSizeInBits() / 8;
    int quantitySamples = sizeChunk / numBytesPerSample;
    long baseTime = quantitySamples * index;

    Map<Long, List<TimePitchValue>> mapListTimePitchValue = new LinkedHashMap<>();

    IntStream.range(0, quantitySamples).mapToObj(time -> {
      List<TimePitchValue> listTimePitchValue = listChunkDTO.stream().map(chunkDTO -> {
        int value = extractValue(chunkDTO.getChunk(), numBytesPerSample, time);
        return new TimePitchValue(chunkDTO.getPitch(), baseTime + time, value);
      }).collect(Collectors.toList());

      mapListTimePitchValue.put(baseTime + time, listTimePitchValue);

      return listTimePitchValue;
    });

    return mapListTimePitchValue;
  }

对于每个time值，将生成一个名称为List<TimePitchValue>的listTimePitchValue，并且我希望将指定的listTimePitchValue与baseTime + time中的指定mapListTimePitchValue关联。

问题是，是否可以直接从Map<Long, List<TimePitchValue>>返回排序后的IntStream？（以前没有创建Map<Long, List<TimePitchValue>> mapListTimePitchValue = new LinkedHashMap<>();，以后没有创建mapListTimePitchValue.put(baseTime + time, listTimePitchValue);）

这对您有用吗？
