『》』什么是单态类？ 『《』单态类是一种创建性模型类,它用来确保只产生一个实例,并提供一个访问它的全局切入点。 『》』在Ruby语言中，如何写第一个单态类代码？ 『《』我们给出一个具体单态类DbConnect代码（线程安全）： require 'singleton' class DbConnect include Singleton end 『》』如何调用我们上述的单态类DbConnect？ 『《』我们通过irb来实际操作一下： 『》』在Ruby语言中，如何写第二个单态类代码？ 『《』我们给出第二个具体单态类DbConnect代码（非线程安全）： DbConnect = Object.new class def foo ; end def bar ; end end 『》』如何调用我们第二个单态类DbConnect？ 『《』我们还是通过irb来实际操作一下： 『》』在Ruby语言中，如何写第三个单态类代码？ 『《』我们给出第三个具体单态类DbConnect代码（非线程安全）： module DbConnect def eins;end def zwei;end module_function :eins,:zwei end 等价代码为： DbConnect = Module.new class def eins;end def zwei;end end module DbConnect private def eins;end def zwei;end end
