在C++中实现持久类

REALIZING PERSISTENT CLASSES IN C++

摘要: 文中用Ｃ＋＋定义并实现了一种ＰｅｒｓｉｓｔＣｌａｓ类，它能永久保存和恢复．并且所有它的子类也能永久保存和恢复．从而将Ｃ＋＋中的临时类转化成持久类，实现了ＯＯＤＢ的一个主要功能．

Abstract: A class named PersistClass is realized in C++. It can be persistently stored and recovered, and so can be all its subclasses. By this way, temporal classes in C++ are converted into persistent classes,thus realizing a main function of OODB.
