Class Names

Ruby

Hi, I was wondering how I can reffer to a class outside of my class, but
it has the same name. Hopefully the following code will make it more
clear:

module Test
class File
def print_file
# I don’t want to call Test::File.open here:
File.open(‘test.rb’, “r”) { |f| puts f.read }
end
end
end

Test::File.new().print_file

Test::File.new().print_file

Prefix with ::, eg ::File.open.

    ::File.open('test.rb', "r") { |f| puts f.read }

The :: means look up the constant in the top level scope.
