std::tr1::bind()和std::tr1::function()的例子

[TOC] # 線程庫的常規設計 庫提供一個`Thread`的基類，裏面有（純）虛函數`Thread::run()`,我們需要從`Thread`派生一個基類,然後覆寫`run()·函數，然後`start()`運行線程。 # 基於std::tr1::bind()和`std::tr1::function()`的設計 ``` class Thread { public: typedef std::tr1::function<void()> TrCallBack; Thread(TrCallBack &tcb); private: void start(); void run(); TrCallBack _tcb; }; Thread::Thread(TrCallBack &tcb):_tcb(tcb) {} void Thread::start() { // do something to call run. } void Thread::run() { _tcb(); } class Foo { public: void func1(); void func2(int a); void func3(string b); }; int main(int argc,char **argv) { Foo foo; Thread t1(std::tr1::bind(&Foo::func1, &foo)); Thread t2(std::tr1::bind(&Foo::func2, &foo,1)); Thread t3(std::tr1::bind(&Foo::func3, &foo,"hey guy")); t1.start(); t2.start(); t3.start(); return 0; } ```
