[Insight-developers] proper way to test for a superclass?

[Michael Stauffer (Circular Logic)]

Hi Luis,
 
Yes sorry, that wasn't clear. 
 
For example, I'd like to test at runtime that an object is a
MatrixOffsetTransformBase class, or a subclass thereof, to make sure it
has certain member functions. The issue comes from reading a transform
file using the transform file reader, and wanting to make sure the
output object is of the type or a subclass.
 
I can't see in the TransformFileReader class how I can tell or control
what kind of transform type it's returning, except for trying a dynamic
class. Am I missing some way to do so more properly? The documentation
doesn't seem to cover this.
 
Cheers,
Michael

Hi Michael,

What do you mean by a "minimum superclass" ?

Please explain.

Hi,

What's the proper way in ITK to test for a minimum superclass? I could
do a dynamic cast and check for NULL - is that acceptable? Thanks.

Cheers,
Michael
