Nebula2探秘附件:nutildef与nkernelinfo的代码

前端之家收集整理的这篇文章主要介绍了Nebula2探秘附件:nutildef与nkernelinfo的代码前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

nutildef.h中主要定义了运行Nebula2程序所需要的最小依赖以及简化声明和使用Nebula2对象的工具宏,代码如下:

/* ************************************************************************** */
/* Nebula2-TutorialUtils */
/* nKernelInfo-Nebula2实用工具宏及静态库 */

nkernelinfo类主要是对第3章代码的整理,目前支持察看Nebula2的Class列表和当前NOH中的对象两项功能
nkernelinfo.h代码如下:

/* ************************************************************************** */
/* Nebula2-TutorialUtils */
/* nKernelInfo-Nebula2内核信息调试器 */
/* author:happykevins */
/* ************************************************************************** */
#pragma once
#include

#include

#include
" util/nhashlist.h "

// 使用标准输出流(否则输出到Nebula2的日志系统)
#ifdefKS_USE_STDOUT
#define ks_printprintf
#else
#define ks_printn_printf
#endif

class nKernelInfoHelper: public nRoot
{
public :
/// 构造nKernelInfoHelper
nKernelInfoHelper(nKernelServer * _ks = nKernelServer::Instance());
/// 设置KernelServer实例
void SetKernelServer(nKernelServer * _ks);
/// 将指定NOH分支的当前信息输出到Nebula日至系统
void LogNOH( const char * szRootPath);
/// 将当前的类列表输出到Nebula日至系统
void LogCLS();

protected :
nKernelServer
* ks;
};

nkernelinfo.cpp代码如下:
