什么是“序列化"?编程中的对象? [英] What is a "serialized" object in programming?

问题描述

我到处都看到过序列化"一词，但从未解释过.请解释一下这是什么意思.

I've seen the term "serialized" all over, but never explained. Please explain what that means.

推荐答案

串行化通常是指将抽象数据类型转换为字节流的过程(有时也可以序列化为文本，XML或CSV或其他格式.重要的是，它是一种简单的格式，可以在不了解数据所代表的抽象对象的情况下进行读取/写入.将数据保存到文件或通过网络传输时，不能仅存储MyClass对象，而只能存储字节.因此，您需要获取重建对象所需的所有数据，并将其转换为可以写入目标设备的字节序列，并在以后的某个时间点读回并反序列化，以重建对象.

Serialization usually refers to the process of converting an abstract datatype to a stream of bytes (You sometimes serialize to text, XML or CSV or other formats as well. The important thing is that it is a simple format that can be read/written without understanding the abstract objects that the data represents). When saving data to a file, or transmitting over a network, you can't just store a MyClass object, you're only able to store bytes. So you need to take all the data necessary to reconstruct your object, and turn that into a sequence of bytes that can be written to the destination device, and at some later point read back and deserialized, reconstructing your object.
