A simple question about setters

[Dark_Tower]

Hi, I'm programming a class that handles a certain types of parameters. And also can save/load them from disk. Well for each parameter I have it's corresponding setter and getter method all similar to the following:

double ProcParamsHandler::sizeH()
{
    return m_sizeh;
}
 
void ProcParamsHandler::setSizeH(double newSizeH)
{
   if (newSizeH < 0 || newSizeH > MAX_SIZE_H)
          newSizeH = INVALID_SIZE;
   m_sizeH = newSizeH;
}

double ProcParamsHandler::sizeH()
{
    return m_sizeh;
}

void ProcParamsHandler::setSizeH(double newSizeH)
{
   if (newSizeH < 0 || newSizeH > MAX_SIZE_H)
          newSizeH = INVALID_SIZE;
   m_sizeH = newSizeH;
}

I also have implemented a method to set the value for all the parameters (like the setter above) all in just a simple call. Well my question is: what's the common way to implement this "global" setter: calling its setter for each parameter or putting directly the code of its corresponding setter for each parameter?

Thanks.
