访问ruby中的对象内存地址..? [英] Accessing objects memory address in ruby..?

问题描述

Ruby 有没有办法获取对象的内存地址?

(i = 5)

是否可以得到那个对象5的内存地址?

我一直在努力解决这个问题.

解决方案

是.

来自摆弄 Ruby 的小提琴":><块引用>

您可以通过获取对象 id 并按位向左移动来获取对象的实际指针值.这将为您提供内存中 ruby​​ 对象的指针(或内存位置)."

使用您的 i = 5 示例，可以这样做:

i = 5i_ptr_int = i.object_id <<1=>22

"在 Ruby 中，为什么inspect() 打印出的对象ID 与object_id() 给出的不同?" 有更多关于object_id 的信息，包括对实现底层的 C 源代码的简要介绍，您可能会觉得有帮助.

看看Fiddle" 其他一些你可以做的很酷的事情.

Is there any way in Ruby to get the memory address of objects?

(i = 5)

Is it possible to get the memory address of that object 5?

I have been trying to get this over some time.

解决方案

Yes.

From "Fiddling with Ruby’s Fiddle":

"You can get the actual pointer value of an object by taking the object id, and doing a bitwise shift to the left. This will give you the pointer (or memory location) of the ruby object in memory."

Using your example of i = 5 it could be done like so:

i = 5
i_ptr_int = i.object_id << 1
=> 22

"In Ruby, why does inspect() print out some kind of object id which is different from what object_id() gives?" has more info about object_id, including a brief introduction to the C source underlying the implementation which you might find helpful.

Take a look at "Fiddle" for some other cool things you can do.
