  - ### ADNameSampleStream

    public ADNameSampleStream(ObjectStream<String> lineStream, boolean splitHyphenatedTokens)
    Initializes a new `ADNameSampleStream` stream from a `ObjectStream<String>`, that could be a `PlainTextByLineStream` object.
    Parameters:
      `lineStream` - An `ObjectStream<String>` as input.
      `splitHyphenatedTokens` - If `true` hyphenated tokens will be separated: "carros-monstro" > "carros" "-" "monstro".

  - ### ADNameSampleStream

    @Deprecated(forRemoval=true) public ADNameSampleStream(InputStreamFactory in, String charsetName, boolean splitHyphenatedTokens) throws IOException
    Deprecated, for removal: This API element is subject to removal in a future version.
    Initializes a new `ADNameSampleStream` from an `InputStreamFactory`
    Parameters:
      `in` - The Corpus `InputStreamFactory`.
      `charsetName` - The `charset` to use for reading of the corpus.
      `splitHyphenatedTokens` - If `true` hyphenated tokens will be separated: "carros-monstro" > "carros" "-" "monstro".
    Throws:
      `IOException`

- ## Method Details

  - ### read

    public NameSample 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<NameSample>`
    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<NameSample>`
    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<NameSample>`
    Throws:
      `IOException` - Thrown if there is an error during closing the stream.
