Start with:
class C
def self.class_callme
internal_helper
end
def instance_callme
C.internal_helper
end
def self.internal_helper
puts "I'm not needed by the outside world."
end
end
My first instinct was to make internal_helper protected:
class << self
protected
def internal_helper
puts "I'm not needed by the outside world."
end
end
However, instance_methods (such as instance_callme) can't call protected
class methods.
Is there some other idiomatic Ruby way to, er, protect internal_helper, or
another way to call it from instance_callme? Or do I just have to do it
through lack of documentation with :nodoc:?
