014 * RaspberryPiSimulatorConnectionConfig object, but it's actually persisting the
015 * RaspberryPiAdapter.
016 * <p>
017 * This class is invoked from jmrix.JmrixConfigPaneXml on write, as that class
018 * is the one actually registered. Reads are brought here directly via the class
019 * attribute in the XML.
