我想产生一个template struct宏来生成模板定义

#define REGISTER_FUNCTOR(type, func) \ 
    template <OWNER> \ 
    struct writeCharFunctor { \ 
    void operator(PropInfoType::iterator& it, PdxWriterPtr pw)() { \ 
     MemberProperty<OWNER,type> *ptr = (MemberProperty<OWNER, type> *)it->second; \ 
     const char *propertName = ptr->m_propertyName.c_str(); \ 
     if (!ptr->m_getterFn) { \ 
     throw; \ 
     } \ 
     pw->###func(propertName,(pOwner->*(ptr->m_getterFn))()); \ 
    } \ 
    }; 

    REGISTER_FUNCTOR(char,writeChar); 

但我收到编译器错误error C2061: syntax error : identifier 'OWNER' 我的函数名是对每种类型不同的多种定义,所以不能直接使用模板参数(或有办法做到这一点)

那应该是template <class OWNER>template <typename OWNER>
