Boost中的一些实用技术-白红宇

类型推断：

#include 
     
      #include 
      
       #include 
       
        #include 
        
         using namespace std;vector
         
           func(){	vector
          
            v(10); return v;}int _tmain(int argc, _TCHAR* argv[]){ BOOST_TYPEOF(2.0) x=2.0*3; BOOST_AUTO(years,2+3); BOOST_AUTO(&a , new double[11]); BOOST_AUTO(p , new string("hello")); BOOST_AUTO(v , func()); return 0;}

不能复制的类

#include
     
      using namespace std;//不能复制的类class demo : public boost::noncopyable{};int _tmain(int argc, _TCHAR* argv[]){		demo a;	demo b;	//a=b;	//a(b);	return 0;}

//向typeof注册自定义类型

#include 
     
      #include 
      
       #include 
       
        #include
        
         #include BOOST_TYPEOF_INCREMENT_REGISTRATION_GROUP()using namespace std;//向typeof注册自定义类型// namespace ex{	class demo_class{		int a,b;	};}BOOST_TYPEOF_REGISTER_TYPE(ex::demo_class)int _tmain(int argc, _TCHAR* argv[]){		BOOST_AUTO(x, make_pair("test",ex::demo_class()));	cout<
         
          <

赋值：

      #include 
      
       #include 
       
        #include 
        
         #include 
         #include 
          
           int _tmain(int argc, _TCHAR* argv[]){ using namespace boost::assign; std::vector
           
            v; v+=1,2,3,4,5,9*10; std::set
            
              s; s+="cpp","java","c","python"; std::map
             
              m; m+=std::make_pair(1,"hello"),std::make_pair(2,"rollen");}

#include 
     
      #include 
      
       #include 
       
        #include 
        
         #include 
         
          #include 
          #include 
           
            using namespace std;int _tmain(int argc, _TCHAR* argv[]){ using namespace boost::assign; std::vector
            
             v; push_back(v)(1)(2)(3)(4); push_back(v),1,2,3,4,5; push_back(v),1,(2),3; list
             
               l; push_front(l)(1)(2); set
              
               s; insert(s)(12.23)(1.23); map
               
                m; insert(m)(1,"name")(2,"age");}
