code: public void setOutputDataObject( Object outputDataObject ) {
          dataObject = outputDataObject;
          if (outputDataObject instanceof Vector) {
              if (((Vector) outputDataObject).capacity() == 0)

      }
docs: Define the output data object. The output data object is the kind of result that the reader
  will give. This can be for example:
  <ul>
  <li> when you need to elaborate the data, a double matrix, so the odo would be <b>new
  double[][]</b></li>
  <li> when you need to visualize the data, a floatbuffer, so the odo would be <b>new
  {@link FloatBuffer}</b></li>
  </ul>
  
  @param outputDataObject the output data object
