Re: Re: Large Java classes wanted

I see. Associativity and cohesiveness are concepts that are not inherent in
the software. I assume you're trying to find an indirect means of doing so,
say for example by using dags or something similar?

You could generate large classes by "reverse refactoring". Start with a well
designed, well refactored set of classes and then merge them into one large
class. Run your system over it and see if you get the original classes
back.
