To bring the real problem more upfront. Up to now, inheriting classes is all about processing (the output channel) but not about retrieving (the input channel). However, though a new type can advance from an existing type if it just needs to provide some few more methods, it can not advance from an existing type if it needs to support some few other input formats--even if they all convert to the inherited type easily. The input channel is completely forgotten.
