[Vxl-maintainers] dynamic_cast in vsol, vtol

[Matt L. <ml...@le...>]

  Does anyone object to the replacement of the cast_to_*() functions in
vsol and vtol with dynamic_cast?  

  I know this issue has come up before, and I think the decision was to
allow RTTI outside of the "core".  The problem we are having with the
cast_to_*() functions is that each class must know about all of its
subclasses.  If we wish to add a new derived classes we must add a
cast_to_*() function to the parent.  This is a problem, for example,
when we try to create a local library of classes that extend vsol.

  As a result, we might attempt to update vsol and vtol to use
dynamic_cast unless anyone can see a reason why this would be a bad
idea.

Thanks,
