The garbage collection list in gclist holds objects of type GCInfo. The GCInfo class is shown here:// This class defines an element that is stored// in the garbage collection information list.//temp

GCPtr overloads operator=( ) twice: once for the assignment of a new address to a GCPtr pointer, and once for the assignment of one GCPtr pointer to another. Both versions are shown here:// Overload

If you are allocating an array using new, then you must tell GCPtr this fact by specifying its size when the GCPtr pointer to that array is declared. For example, here is the way to allocate an array

The following program load tests GCPtr by repeatedly allocating and discarding objects until free memory is exhausted. When this occurs, a bad_alloc exception is thrown by new. Inside the exception ha

   麻痹的不会在优快云上贴图片，只好用文字来表达了实际上，这个最简单的垃圾回收器的实现，我们只用关心，两个指针，以及一个结构，在我的代码中如下 // 定义只在本文件中使用的静态变量，并初始化static BYTE* m_begin = (BYTE*)HeaderSize;static BYTE* m_end = (BYTE*)HeaderSize; //

/*对内存池的需求分析：   我们希望我们开发的某个应用可以使用以一块固定的内存空间   这块内存空间是一开始申请好的，   所有的内存使用都是在这块空间内完成，可以避免和其他应用的内存使用相互冲突      可以对应用使用的内存情况进行部分统计   可以在应用退出后自动对内存进行回收（我们假设用户的习编程惯是不良好的，有可能产生内存泄露）尤

The garbage collector uses four classes: GCPtr, GCInfo, Iter, and OutOfRangeExc. Before examining the code in detail, it will be helpful to understand the role each class plays.GCPtr GCPtr is a

Before implementing a garbage collector for C++, it is necessary to decide what garbage collection algorithm to use. The topic of garbage collection is a large one, having been the focus of serious ac

Using a GCPtr is quite easy. First, include the file gc.h. Then, declare a GCPtr object, specifying the type of the data to which it will point. For example, to declare a GCPtr object called p that ca

前一段时间工作需要，在收集资料的过程中看了 许世 伟的“最袖珍的垃圾回收器”一文原文http://blog.youkuaiyun.com/xushiweizh/archive/2006/11/19/1396573.aspx但有几方面觉得不太合适，自己罗嗦几句吧第一 BLOG里的代码有明显的错误，没有更正第二 写的还是不够好理解吧，可能是自己水平太差，反正我反复看了不下十遍才基本看懂第三

Comparing the Two Approaches to Memory Management Before developing a garbage collector for C++, it is useful to compare garbage collection to the manual method that is built-in to C++. Normally, th

The use of dynamically allocated memory must be managed, because it has a tremendous effect on the performance of your programs. The current trend in handling dynamic memory seems to be shifting towar

What About auto_ptrAs many readers will know, C++ defines a library class called auto_ptr. Because an auto_ptr automatically frees the memory to which it points when it goes out of scope, you might

 GCPtr is the heart of the garbage collector. It implements a new pointer type that keeps a reference count for objects allocated on the heap. It also provides the garbage collection functionality t
