c++ - 错误：在 C++ 中不匹配 operator=

Question

嗨，我在使用 g++ 4.1.2 编译时遇到此错误

“错误：operator= in 不匹配” ((PoolElementList*)this)->PoolElementList::i_currentElement = ((PoolElementList*)this)->PoolElementList::i_elementList.std::vector<_Tp, _Alloc>::end _Tp = ModifyTerminationPointReqInfo*, _Alloc = std::allocator

PoolElements 的定义如下：

template <class Element, Element *intialElementPtr>
class PoolElementList
{
        GenericMemoryPool <Element, intialElementPtr> *i_elementPoolPtr;

        vector <Element *> i_elementList;
        vector <Element *> i_currentElement;
public:

  //Define a constructor that takes in a pointer of the pool.
        PoolElementList(GenericMemoryPool <Element, intialElementPtr> *elementPool):
        i_elementPoolPtr (elementPool)
        { 
                i_currentElement = i_elementList.end();   //error is here**
        };

请有人可以解释这可能有什么问题。（这是在 g++ 2.9.x 中编译的）

Answer 1

如果（正如您在评论中所说）您打算i_currentElement成为 a std::vector<Element *>::iterator，那么您必须将其声明为 one。只需更换

vector <Element *> i_elementList;

和

vector <Element *>::iterator i_elementList;
