基于对象风格的线程类封装

基于对象风格的编程思想和面向对象的编程思想不同。面向对象使用纯虚函数为派生类提抽象接口，是一种抽象类（实现回调）；而基于对象使用具体类，在类里面通过注册函数实现回调；若是C风格的编程思想，则是定义全局的注册函数指针。
基于对象风格的线程类封装代码如下：
类头文件：

//start from the very beginning,and to create greatness//@author: Chuangwei Lin//@E-mail：[e-mail]//@brief： 基于对象风格的线程类封装#include <pthread.h>#include <iostream>#include <boost/function.hpp>#include <boost/bind.hpp>#ifndef _LCW_THREAD_H_#define _LCW_THREAD_H_//线程基类class lcw_thread{public:    //重定义新类型    typedef boost::function<void ()> LCW_Function;    //构造函数，关键字explicit使其只能显式调用    explicit lcw_thread(const LCW_Function& func);    ~lcw_thread();//析构函数       void Start();    void Join();    void SetAutoDelete(bool AutoDelete);private:    static void* Thread_Routine(void* arg);    void Run();    LCW_Function func_;    pthread_t lcwid;        bool AutoDelete;//是否自动销毁};#endif

类实现函数：

//start from the very beginning,and to create greatness//@author: Chuangwei Lin//@E-mail：[e-mail]//@brief： 基于对象风格的线程类封装#include "lcw_thread.h"using namespace std;lcw_thread::lcw_thread(const LCW_Function& func) :func_(func) ,AutoDelete(false){    cout << "构造函数lcw_thread" << endl;}lcw_thread::~lcw_thread(){    cout << "析构函数lcw_thread" << endl;}void lcw_thread::Start()//启动线程{    pthread_create(&lcwid,NULL,Thread_Routine,this);//this指针是参数}void lcw_thread::Join(){//函数pthread_join用来等待一个线程的结束    pthread_join(lcwid,NULL);}void* lcw_thread::Thread_Routine(void* arg){//参数arg其实是this指针    lcw_thread* lcwthread = static_cast<lcw_thread*>(arg);//指向派生类指针转化为基类对象指针    lcwthread->Run();    if(lcwthread->AutoDelete)//    {        delete lcwthread;//销毁线程    }    return NULL;}void lcw_thread::SetAutoDelete(bool AutoDelete_)  {    AutoDelete = AutoDelete_;//设置是否自动销毁}void lcw_thread::Run(){    func_();}

回调函数和测试函数：

//start from the very beginning,and to create greatness//@author: Chuangwei Lin//@E-mail：[e-mail]//@brief： 基于对象风格的线程类封装#include "lcw_thread.h"#include <unistd.h>using namespace std;//线程回调函数void lcw1(){    cout << "lcw1回调" << endl;} void lcw2(int count){    for(int i = 1;i <= count;i++)    {        cout << "lcw2第"<< i << "次调用" <<endl;    }}int main(int argc, char const *argv[]){    //创建线程,lcw为初始化函数    lcw_thread t1(lcw1);    lcw_thread t2(boost::bind(lcw2,5));    t1.Start();    t2.Start();    t1.Join();    t2.Join();    return 0;}

运行结果如下：
