Mad snippet of the day (too much power for a useless idea…)

Especially written for a servlet container… just guess what it does…

public <E>E toObject(HttpServletRequest request, Class<E> type)
                 throws InstantiationException, IllegalAccessException {
  E inst = type.newInstance();
  Method[] mets = inst.getClass().getDeclaredMethods();
  for(Method m : mets){
    if(m.getName().startsWith("set"))try{
       String varName = m.getName().
                           substring(m.getName().indexOf("set")+3);
       varName = Character.toLowerCase(varName.charAt(0))+
                                         varName.substring(1);
       String val = request.getParameter(varName);
       if(m.getParameterTypes()[0]==Integer.class)
           m.invoke(inst, Integer.valueOf(val));
       if(m.getParameterTypes()[0]==Boolean.class)
           m.invoke(inst, Boolean.valueOf(val));
       if(m.getParameterTypes()[0]==String.class)
           m.invoke(inst, val);
      }catch(Exception e){e.printStackTrace();continue;}
     }
   return inst;
}
