  - ### parseReferences

    public String[] parseReferences(String name, InputStream in, BHSDCodec codec, int count, String[] reference) throws IOException, Pack200Exception
    Parses count references from `in`, using `codec` to decode the values as indexes into `reference` (which is populated prior to this call). An exception is thrown if a decoded index falls outside the range [0..reference.length-1].
    Parameters:
      `name` - the band name
      `in` - the input stream to read from
      `codec` - the BHSDCodec to use for decoding
      `count` - the number of references to decode
      `reference` - the array of values to use for the references
    Returns:
      Parsed references.
    Throws:
      `IOException` - if a problem occurs during reading from the underlying stream
      `Pack200Exception` - if a problem occurs with an unexpected value or unsupported Codec

  - ### parseReferences

    public String[][] parseReferences(String name, InputStream in, BHSDCodec codec, int[] counts, String[] reference) throws IOException, Pack200Exception
    Parses count references from `in`, using `codec` to decode the values as indexes into `reference` (which is populated prior to this call). An exception is thrown if a decoded index falls outside the range [0..reference.length-1]. Unlike the other parseReferences, this post-processes the result into an array of results.
    Parameters:
      `name` - TODO
      `in` - the input stream to read from
      `codec` - the BHSDCodec to use for decoding
      `counts` - the numbers of references to decode for each array entry
      `reference` - the array of values to use for the references
    Returns:
      Parsed references.
    Throws:
      `IOException` - if a problem occurs during reading from the underlying stream
      `Pack200Exception` - if a problem occurs with an unexpected value or unsupported Codec
