从这个问题开始
快速回顾一下,我需要将指向函数的指针传递给第 3 方库中名为 moveset 的类的构造函数,其定义为
template <class Space>
moveset<Space>::moveset(particle<Space> (*pfInit)(rng*),
void (*pfNewMoves)(long, particle<Space> &,rng*),
int (*pfNewMCMC)(long,particle<Space> &,rng*))
该库提供的示例是简单地为 pfInit 等定义全局函数,我们称它们为 f、g 和 h。然后从控制器类中调用 smc::moveset Moveset(f,g,h);
我试图使用 boost:bind 来实现这个建议。不幸的是,我正在努力让它发挥作用。
class IK_PFWrapper
{
public:
IK_PFWrapper(Skeleton* skeleton, PFSettings* pfSettings) ;
smc::particle<cv_state> fInitialise(smc::rng *pRng);
...
} ;
在控制器类中
IK_PFWrapper testWrapper (skeleton_,pfSettings_);
boost::function<smc::particle<cv_state> (smc::rng *)> f = boost::bind(&IK_PFWrapper::fInitialise, &testWrapper,_1) ;
// the 2nd and 3rd argument will be eventually be defined in the same manner as the 1st
smc::moveset<cv_state> Moveset(f, NULL, NULL);
产生的编译器错误是,
Algorithms\IK_PFController.cpp(88): error C2664: 'smc::moveset<Space>::moveset(smc::particle<Space> (__cdecl *)(smc::rng *),void (__cdecl *)(long,smc::particle<Space> &,smc::rng *),int (__cdecl *)(long,smc::particle<Space> &,smc::rng *))' : cannot convert parameter 1 from 'boost::function<Signature>' to 'smc::particle<Space> (__cdecl *)(smc::rng *)'
with
[
Space=cv_state
]
and
[
Signature=smc::particle<cv_state> (smc::rng *)
]
and
[
Space=cv_state
]
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
非常感谢任何帮助
