Greetings, I have a class that implements the iterator protocol, and tokenises a string into a series of tokens. As well as the token, it keeps track of some information such as line number, source file, etc.
for tokens in Tokeniser(): do_stuff(token) What I want is to be able to wrap the tokeniser to add functionality to the base parser without subclassing, e.g. for tokens in processor(Tokeniser()): do_stuff(token) Sort of Decorator pattern, so that I can chain more processors, but I cannot think how to implement it. Any clues for me? Thanks TomH
