Have the computational hygiene, if you like, to only go through accessors, only go through methods that are actually provided to you as you do this.
请大家注意计算卫生,如果你喜欢这么说的话,只通过访问器访问数据,当你访问数据的时候,通过提供给你的方法来访问。
You can compel the compiler to treat some value as a different type of value, at least if it makes intuitive sense that that should be possible.
你可以控制编译器处理,不同类型的数据,至少我们凭直觉,它应该是可能的。
When we're just interacting with idol, with the interactive editor or sorry, interactive environment if you like, that's what you expect. What's happening is that we're typing in something, an expression it doesn't know how to deal. It's raising the exception, but is this simply bubbling up at the top level saying you've got a problem.
就发生了其中之一是吧,当你在交互数据处理或者是在交互编辑器,抱歉,任何你喜欢的交互式环境中,你可能会遇到这些,如果你在输入什么内容,譬如一个它不知道怎么处理的表达式,它就会报一个异常,但这是否是简单的,把你遇到的问题冒到最顶层呢?
As I said, I would prefer to do something that uses an accessor that I just wrote.
来完成这个操作,因此p,Cartesian是一种访问器,它可以访问里面的数据。
