[Alephmodular-devel] Some questions on defining CFileType

[Br'fin <br...@ma...>]

On multiply typed elements
After a quick bit of thinking, do we have need for types with multiple 
attributes? And how should that be handled? For instance, a 
CMarathon2MapType is both a CMapType and a CMarathon2Type. I take this 
to mean two possible implementations:

1) CMarathon2MapType is a direct subclass of CFileType and implements 
IMapType and IMarathon2Type interfaces.

2) The is_a hierarchy is maintained in a different way. Like real 
attributes on the object.

I admit, on typing I'm trying to figure out if the class is 
C<whatever>Type and is essentially a singleton. What is a decent way of 
referring to one specific type or another?

A CFileTypeFactory that offers GetTypeFor("<whatever>") with a hash or 
dictionary within?
