C+＋并发类成员函数调用（练习1）

一般类成员函数开线程格式 std::thread t1(&类名::函数，&实例化对象，参数....) ||std::thread t1(std::bind(&&类名::函数，&实例化对象，参数....))

#include <iostream>
#include <mutex>
#include <thread>
#include <vector>
#include <string>
#include <condition_variable>
#include <future>


template<typename T>
class vector_safe
{
public:
    vector_safe():ready(false),proccess(false){}
public:
    void push(T& value)
    {
        std::unique_lock<std::mutex> m_guard(mut);
        vec.push_back(value);
        ready=true;
        m_guard.unlock();
        condit_va.notify_one();
    }
    void get_and_pop(T& value)
    {
        std::unique_lock<std::mutex> m_guard(mut);
        condit_va.wait(m_guard,[this](){return ready;});//wait-------线程完毕数据；
                       
        value=vec.front();
        vec.pop_back();
        proccess=true;
         m_guard.unlock();
    
    }
private:
    std::vector<T> vec;
    std::mutex mut;
    std::condition_variable condit_va;
    bool ready;
    bool proccess;

};
vector_safe<std::string> obj;

int main()
{
    
        std::string str1("this is dream");
        std::string str2("没覆盖?");
    std::thread t1(std::bind(&vector_safe<std::string>::push,&obj,std::ref(str1)));
    std::thread t2(std::bind(&vector_safe<std::string>::get_and_pop,&obj,std::ref(str2)));
        t1.join();
        t2.join();
        std::cout<<str2<<std::endl;
        return 0;
}

运行结果：
xcode 7.2
this is dream
Program ended with exit code: 0
