一元素的类型用于泛型接口的容器使用的。

    typedef GValue generic_value;

备注

描述类型存储描述的元素值用于带有泛型接口的容器类使用此模板的 GValue 类型的对象。

示例

// cliext_hash_map_generic_value.cpp 
// compile with: /clr 
#include <cliext/hash_map> 
 
typedef cliext::hash_map<wchar_t, int> Myhash_map; 
int main() 
    { 
    Myhash_map c1; 
    c1.insert(Myhash_map::make_value(L'a', 1)); 
    c1.insert(Myhash_map::make_value(L'b', 2)); 
    c1.insert(Myhash_map::make_value(L'c', 3)); 
 
// display contents " [a 1] [b 2] [c 3]" 
    for each (Myhash_map::value_type elem in c1) 
        System::Console::Write(" [{0} {1}]", elem->first, elem->second); 
    System::Console::WriteLine(); 
 
// construct a generic container 
    Myhash_map::generic_container^ gc1 = %c1; 
    for each (Myhash_map::value_type elem in gc1) 
        System::Console::Write(" [{0} {1}]", elem->first, elem->second); 
    System::Console::WriteLine(); 
 
// get an element and display it 
    Myhash_map::generic_iterator gcit = gc1->begin(); 
    Myhash_map::generic_value gcval = *gcit; 
    System::Console::WriteLine(" [{0} {1}]", gcval->first, gcval->second); 
    return (0); 
    }
