Doubt at ActionController::Routing::RouteSet::NamedRouteCollection#clear!
I would like to know if anyone could explain me something:
def clear!
@routes = {}
@helpers = []
@module ||= Module.new
@module.instance_methods.each do |selector|
@module.class_eval { remove_method selector }
end
end
The thing I don''t understang clearly it''s why
@module.instance_methods.each do ... it''s done since when we create an
anonymous Module it has none instance methods:
irb(main):017:0* m = Module.new
=> #<Module:0x5be78>
irb(main):018:0> m.instance_methods
=> []
Any suggestions?
