How to call private class method?

[estebanjang]

Hi,
In the following code, how can I call "Hello.jane" method?

class Hello
def Hello.jane
puts "I am jane"
end
private_class_method :jane
end

All the following generate NoMethodError:

[1] From within class body
class Hello
Hello.jane
end

[2] From another class method
class Hello
def Hello.call_jane
Hello.jane
end
end
Hello.call_jane

[3] From an instance
class Hello
def call_jane2
Hello.jane
end
end
a = Hello.new
a.call_jane2

Is there any context where I can call Hello.jane?
Also, I am using private_class_method, since the "private" keyword
doesn't seem to have any effect on class methods. Am I missing
something?
Thanks,

-Steve

private_class_method :jane

Hello.send :jane

will work, send also works with private methods.

class Hello
def Hello.call_jane
jane
end
end

Hello.call_jane

works for me also.

Hello.send :jane
=20
will work, send also works with private methods.

I believe that will fail under 1.9 though, where send no longer calls
private methods. IIRC the method you'll need there is 'funcall' instead
of 'send'.

"Private" messages can only be send to self.
If you want to send such message somewhere else, just self !

Hello.instance_eval { jane }

Within the block self is Hello.
