摘　　要：C++对象是存活于内存中的,但是由于RAM的易失性,需要将存活于内存中的对象,通过I/O技术及时地交换到外存中,以保证对象的持久存在(对象I/O技术也称为对象的持久化,即Persistence),所以对象I/O技术也成了C++中的一个重要操作。对象I/O技术的实现需要为对象增加一些额外的运行时信息,即RTTI,技术上的复杂性增加了开发人员所理解对象I/O的难度。本文通过对一个对象I/O技术的模拟实现,深入探讨了对象I/O技术的实现机制。C＋＋ object is alive in the memory, but because of RAM volatile, you need to timely switch the survive object in the memory through I/O technology to the external memory in order to ensure the object persistence （object I/O technology is also referred to as object persistence, that is, Persistence）, so the object I/O technology has become an important operation in C＋＋. The realization of Object I/O technology needs to add some additional run-time information, that is, RTTI; technical complexity increased the object I/O difficulties developer understand. In this paper, through object I/O technique simulation, the object I/O technology implementation mechanism is deep discussed.
