静态 CTypedPtrArray< CPtrArray,A*> RailWayInfoArray 的初始化

Question

class RailWayArrayManage
{
public:
virtual ~RailWayArrayManage();
public:
static RailWayArrayManage* Instance(); RailWayElement* getRailWayElement( int nParam, int nOption = 0 );
public:
static RailWayElement* m_currentRailWayElement;private:
static CTypedPtrArray<CPtrArray,RailWayElement*> RailWayInfoArray;
static RailWayArrayManage* _RailWayArrayManage;
RailWayArrayManage();
};
RailWayArrayManage* RailWayArrayManage::_RailWayArrayManage = NULL;           //这句是正确的
CTypedPtrArray<CPtrArray,RailWayElement*> RailWayArrayManage::RailWayInfoArray = NULL;//这个是错误的，这句应怎 么初始化，他是一个静态对变量，必须要初始化 有方法，我会试的，然后贴上来，希望回头看看此。谢谢

Answer 1

CTypedPtrArray <CPtrArray,RailWayElement*> RailWayArrayManage::RailWayInfoArray;
这样就可以了。由于这个是类对象，生成实例就会调用构造函数初始化。
