Hi group. Recently, I've read http://www.visibleworkings.com/little-ruby/Chapter3.pdf http://www.ruby-doc.org/docs/Understanding%20Ruby'... and PickAxe. I'm trying to draw a picture of hierarchy for the following: class Foo @@k = 20 end class Bar < Foo @j = 10 def initialize @i = 0 end end b = Bar.new I understand how to draw hierarchy if it were not for class variables: Class ^ | +-------+ | | (Foo) <-(Bar) ^ ^ - Bar's class methods | | Foo <- Bar ^ - j and Bar's instance methods | b - i In this picture parenthesis represents meta class. Upward arrows represents 'class', while leftward arrows represents 'inherits'. But, I have no idead where the class variable k should belong to. k is shared by Foo and Bar which menas that if k is modified at Foo, then the value of k at Bar will be modified also. That being the case, does k must be drawn under (Foo)? or Class? Thanks. - Minkoo S.
