What kind of inheritance is that?

Ruby

I founded this code at WEBrick library:

class HTTPServer < ::WEBrick::GenericServer
def initialize(config={}, default=Config::HTTP)
super

What kind of inheritance is HTTPServer << ::WEBrick, I don’t undestand
de ::
before. What does it means?

It’s there to make sure the right class is used. Try:

class A
def foo
“a”
end
end

module B
class A
def foo
“ba”
end
end

p A.new.foo
p ::A.new.foo

end

“ba”
“a”
=> nil
