[stem/master] Using enum.__iter__ for values rather than keys
commit da937730bb3aaa303e584eb3e23494703923c46b Author: Damian Johnson <atagar@torproject.org> Date: Sun Nov 20 14:20:13 2011 -0800 Using enum.__iter__ for values rather than keys Enumeration keys are of very limited use. Iteration over an enumeration should give the values instead so swapping values() and __iter__() to be keys() and __iter__(). --- stem/util/enum.py | 14 +++++++------- test/unit/util/enum.py | 6 +++--- 2 files changed, 10 insertions(+), 10 deletions(-) diff --git a/stem/util/enum.py b/stem/util/enum.py index 6ce54d0..6891663 100644 --- a/stem/util/enum.py +++ b/stem/util/enum.py @@ -4,7 +4,7 @@ constructed as simple type listings, ie:
