根据WTPartMaster获取其对应的所有WTPart的方法：

  LatestConfigSpec latestconfigspec = new LatestConfigSpec();
  QueryResult queryresult = ConfigHelper.service.filteredIterationsOf(partMaster, latestconfigspec);

获取小版本的方法：
VersionControlHelper.getIterationIdentifier((Iterated)wtpart).getValue();

      System.out.println(wtpart.getName());
      System.out.println(wtpart.getNumber());
      System.out.println(wtpart.getVersionDisplayIdentifier().getLocalizedMessage(Locale.CHINA));
      System.out.println(wtpart.getVersionDisplayIdentity().getLocalizedMessage(Locale.CHINA));
      System.out.println(wtpart.getVersionDisplayType().getLocalizedMessage(Locale.CHINA));
      System.out.println(wtpart.getVersionIdentifier().getValue());
      System.out.println(wtpart.getVersionInfo().getIdentifier().getValue());
      System.out.println(wtpart.getView().getName());
      System.out.println(wtpart.getViewName());

显示的结果为：

     GOLF_CART
     GC000001
     A.A (Manufactur
     修订 (视图) A.A
     修订 (视图)
     A.A
     A.A

关于WTPart、EPMDocument和CAD图纸的问题

我已知一个WTPart对象，怎么才能得到该对象的CAD图纸呢
有人说是要先得到EPMDocument，那么我怎么从EPMDocument里面拿到这张图纸呢
供参考：
contentholder = ContentHelper.service.getContents(contentholder);

Enumeration enum = ContentHelper.getContentListAll(contentholder).elements();

while (enum != null && enum.hasMoreElements())

{
            ContentItem item = (ContentItem) enum.nextElement();
          
            if (item instanceof ApplicationData)

            {
                ApplicationData appData = (ApplicationData) item;
                ContentServerHelper.service.writeContentStream(appData, pathName + File.separator + appData.getFileName());

             }

}
