It could be dead simple as specifying the class if the different JSON libraries shared a common to/from API selectors, but they don't.
Yes, it would be very good if there was such a thing as a common API for any reader/writer of any format (JSON, CSV, XML, STON, FUEL, ...).
For a reader that is pretty easy, I think. Any reader object should understand
#readFrom: <stream> (binary or character ReadStream as appropriate)
And maybe also
#readFromString: <string> #readFromBytes: <bytearray>
For the writer, I am not so sure. Maybe
#nextPut: <object> toStream: <stream> (binary or character ReadStream as appropriate)
And maybe also
#toString: <object> #toBytes: <object>
Note that the reader and writer objects could be different.
But like I said, I am not so sure about the API. We could try to define a Trait for this.
I'd like to have #readFrom:as: . Some of the mappers instantiate common classes that should be overwritable. Of course this does not apply for e.g. fuel. Norbert
