Re: public_methods on a class

In the defination of class B, the part =93< A" tells ruby that class B
is inheriting from class A.

When class B inherits from class A, all the properties(methods,
instance and class variables) in class A are available to class B

Ex:

class A
   def self.foo
     "FOO"
   end
 end
  class B < A

  end

class C < B

end

C.public_methods(false)

[:foo, :allocate, :new, :superclass]

When we inherit class B in C will result the same...

Thanks,
