如何将对象保存到文件中? [英] How can I save an object to a file?

问题描述

我想将一个对象保存到一个文件中，然后轻松地从文件中读取它.作为一个简单的例子，假设我有以下 3d 数组:

I would like to save an object to a file, and then read it from the file easily. As a simple example, lets say I have the following 3d array:

m = [[[0, 0, 0],
 [0, 0, 0],
 [0, 0, 0]],
[[0, 0, 0],
 [0, 0, 0],
 [0, 0, 0]]]

是否有一个简单的 Ruby API 可以用来实现此目的，而无需编写解析器来解释文件中的数据?在我给出的示例中，这很容易，但是随着对象变得越来越复杂，使对象持久化变得很烦人.

Is there an easy Ruby API that I can use to achieve this without programming a parser to interpret the data from the file? In the example I give it is easy, but as the objects become more complicated, it gets annoying to make objects persistent.
