  Constructor
  Description
  `ADSentenceSampleStream(InputStreamFactory in, String charsetName, boolean includeHeadlines)`
  Initializes a new `ADSentenceSampleStream`.
  `ADSentenceSampleStream(ObjectStream<String> lineStream, boolean includeHeadlines)`
  Initializes a new `ADSentenceSampleStream` from a `ObjectStream<String>`, that could be a `PlainTextByLineStream` object.

  - ### ADSentenceSampleStream

    public ADSentenceSampleStream(ObjectStream<String> lineStream, boolean includeHeadlines)
    Initializes a new `ADSentenceSampleStream` from a `ObjectStream<String>`, that could be a `PlainTextByLineStream` object.
    Parameters:
      `lineStream` - A stream of lines as `String`.
      `includeHeadlines` - If `true` will output the sentences marked as news headlines.

  - ### ADSentenceSampleStream

    public ADSentenceSampleStream(InputStreamFactory in, String charsetName, boolean includeHeadlines) throws IOException
    Initializes a new `ADSentenceSampleStream`.
    Parameters:
      `in` - The `InputStreamFactory` for the corpus.
      `charsetName` - The `charset` to use for reading of the corpus.
      `includeHeadlines` - If `true` will output the sentences marked as news headlines.
    Throws:
      `IOException` - Thrown if IO errors occurred.

- ## Method Details

  - ### read

    public SentenceSample read() throws IOException
    Description copied from interface: `ObjectStream`
    Returns the next `ObjectStream` object. Calling this method repeatedly until it returns `null` will return each object from the underlying source exactly once.
    Specified by:
      `read` in interface `ObjectStream<SentenceSample>`
    Returns:
      The next object or `null` to signal that the stream is exhausted.
    Throws:
      `IOException` - Thrown if there is an error during reading.

  - ### reset

    public void reset() throws IOException, UnsupportedOperationException
    Description copied from interface: `ObjectStream`
    Repositions the stream at the beginning and the previously seen object sequence will be repeated exactly. This method can be used to re-read the stream if multiple passes over the objects are required.

    The implementation of this method is optional.

    Specified by:
      `reset` in interface `ObjectStream<SentenceSample>`
    Throws:
      `IOException` - Thrown if there is an error during resetting the stream.
      `UnsupportedOperationException` - Thrown if the `reset()` is not supported. By default, this is the case.

  - ### close

    public void close() throws IOException
    Description copied from interface: `ObjectStream`
    Closes the `ObjectStream` and releases all allocated resources. After close was called, it's not allowed to call `ObjectStream.read()` or `ObjectStream.reset()`.
    Specified by:
      `close` in interface `AutoCloseable`
    Specified by:
      `close` in interface `ObjectStream<SentenceSample>`
    Throws:
      `IOException` - Thrown if there is an error during closing the stream.
