Hi there,
I am still working my way through MultiByteFileStream tests, and have come across the messages #converter and #converter: . I would like to be able to test these - could someone explain briefly how the converters are used in this class?
In order to convert from bytes to characters and vice versa, MultiByteFileStream uses a TextConverter subclass instance as a helper. The messages #nextFromStream: and #nextPut:onStream: are the main interface between the two.
This guy is loudly crying for a decorator. I wonder when Xtreams could be pushed...
The silly thing is that both MultiByteFileStream and TextConverter convert from wrongly encoded strings to correctly encoded strings.
So it corrects encodings? :P I didn't know that! They are flawless!!!
ZnCharacter[Read|Write]Stream and ZnCharacterEncoder do the correct thing.
