The source and target classes are used by the Converter.canConvert
method. The Converter.canConvert method is used by the Converter factory
to find the correct converter. The reason parameterized types are not
used in this scenario is so you can create converters that handle entire
class hierarchies. If you can think of a way to replace the Class
references with parameters, that would be great. Submit a patch and I
will look it over.
You could submit a patch for your partially-completed ConverterChain
class and maybe someone else will complete it.

I was taking a look at the [convert] component because I have done
some work lately on some handy conversion classes. I'm struggling to
understand why you'd need the getSourceClass() and getTargetClass()
methods if you're using generics.
Also, I've got a class that looks like this:
public class ConverterChain<S,T> implements Converter<S,T>
{
public static<S> ConverterChain<S,S> from(Class<S> sourceType);
public<N> ConverterChain<S,N> append(Converter<T,N> converter);
...
}
I'd like to contribute it, but in my library, I don't have all of
those references to the class objects (source/target). I might check
it in without the source/target stuff implemented.
