[摘要] 通过从程序语言的特性、垃圾回收机制、内存对象的序列化机制到基于区域的内存管理机制分析了内存对象的管理存在的问题,并分析了内存对象的生命周期在内存对象管理中能发挥的作用。提出了基于内存对象的生命周期对内存进行区域化管理的思路,可以从根本上解决垃圾回收问题。

[Abstract] Through analysis of the characteristics of program languages, mechanism of garbage collection, serialization of in-memory data-objects and region-based memory management, most existing problems with memory management are exposed. What’s more, the lifetime of in-memory data objects can be key factor in memory management. Thus a solution is region-based memory management combined with the lifetime of in-memory data objects, which can solve the garbage collection problem.
