Wildcards in typeid

There is a section of code in a library I use that looks like this:

...
     if ( ptype == typeid( Vector< T, 4 > ) )
       {
       This->SetNumberOfComponents(4);
       }
     else if ( ptype == typeid( Vector< T, 5 > ) )
       {
       This->SetNumberOfComponents(5);
       }
...

If there any way to make this more generic by doing something like

 if ( ptype == typeid( Vector< T, ANYTHING > ) )
       {
       This->SetNumberOfComponents(THE_SECOND_TEMPLATE_PARAM);
       }

?

Thanks,

David

Solution

  • We took Roger Pate's suggestion of removing the use of typeid by restructuring a little bit (It was the first comment, so I couldn't mark it as the answer). Thanks for all of the great ideas and discussion!
