Re: get all enum fields and their possible values

2009-10-02 Thread Tuppy Hamper 

and how would this change if the message contained fields that were
repeatable or single messages which contained their own ENUMS. I know
I would have to have a branch to the IF statement that if type ==
MESSAGE, then recurse, but would I have to handle single and repeatble
message fields differently?

Thanks

field-is_repeated() returns true or false.  There's nothing else different
about the descriptors (though the resulting messages are obviously pretty
different).


 Thanks
