static_cast and std::vector

Show all headers | View raw

Hi,

I am attempting to replace lots of C-style casts with static_cast's in 
our code base.  Most of these are simple, but there are a few that I'm 
not sure what to do.

Basically, the problem is shown in the code below.  GetD0/GetD1 are the 
original C-style casts that work fine.  I would like to change these to 
C++ style casts, but the GetDD0/GetDD1 functions do not compile.

Is there a way to do this?  Are there any potential problems I should be 
aware of?

Thanks.

#include <vector>

class Base {};
class Derived0 : public Base {};
class Derived1 : public Base {};

class Y
{
    std::vector<Base*> m_vb[2];

    public:

    void Add(Derived0* d0) { m_vb[0].push_back(d0); }
    void Add(Derived1* d1) { m_vb[1].push_back(d1); }

    const std::vector<Derived0*>* GetD0()
	{ return (const std::vector<Derived0*>*) &m_vb[0]; }
    const std::vector<Derived1*>* GetD1()
	{ return (const std::vector<Derived1*>*) &m_vb[1]; }

    const std::vector<Derived0*>* GetDD0()
	{ return static_cast<const std::vector<Derived0*>*>(&m_vb[0]); }
    const std::vector<Derived1*>* GetDD1()
	{ return static_cast<const std::vector<Derived1*>*>(&m_vb[1]); }

};
