Question

可能重复：
How to break outer cycle in Ruby?

说我有这段代码：

class A

  def initialize
    myMethod()
    print "This should not be printed"
  end

  def myMethod
    #here
  end

end

obj = A.new
print "This should be printed"

是否有任何命令我可以放置而不是“#here”退出'obj'对象并继续下一个语句？（打印“这应该打印”）

Answer 1

throw / catch会这样做：

class A

  def initialize
    catch :init_done do
      myMethod()
      print "This should not be printed"
    end
  end

  def myMethod
    throw :init_done
  end

end

obj = A.new
print "This should be printed"

退出ruby中对象中的所有方法
