模块函数(Module Functions) 你可以使用 module_function 关键字将模块中的方法定义为模块函数,这样它们既可以用作实例方法,也可以直接通过模块名调用。 ruby module MyModule def my_method puts "This is a module function" end module_function :my_method end MyModule.my_method 混入多个模块 你可以在类中混...

def functionName( parameter1, parameter2 = "default value") block return end 函数性方法可以省略 return 语句,这时函数的返回值就是方法中最后一个语句的值,就像Perl的处理一样。省略 Return 语句可以为代码书写带来一些方便,但我们需要谨慎对待。 Ruby的函数可以返回多个值,例如: a, b, c = funca() 错误...
