[英]Initialize an static member in an fully specialized class template
I can't seem to init an static member inside an fully specialized class template! 我似乎无法在完全专业化的类模板中初始化静态成员!
I'm trying to do the following: 我正在尝试执行以下操作:
template<typename Type>
class X
{
};
template<>
class X<int>
{
public:
static int Value;
}
But i can't seem to init the static member, i tried everything like: 但我似乎无法初始化静态成员,我尝试了一切像:
template<>
int X<int>::Value = 0;
It doesn't compile, so any pointers on how to actually do this would be nice ;) 它没有编译,所以任何关于如何实际执行此操作的指针都会很好;)
Edit: the answer beneath is correct but you also need to place the init in the .cpp file and not in the header file. 编辑:下面的答案是正确的,但您还需要将init放在.cpp文件中,而不是放在头文件中。
Thanks for your time, Richard. 谢谢你的时间,理查德。
Don't use template<>
while defining Value
because template<>
is not allowed in member definition of explicitly specialized class[ X<int>
in this case]. 不使用template<>
同时限定Value
,因为template<>
中未明确地专门类的成员定义允许[ X<int>
在这种情况下]。 Moreover you are missing a semicolon after }
此外,你错过了一个分号}
This works for me : 这对我有用 :
template<typename Type>
class X
{
};
template<>
class X<int>
{
public:
static int Value;
};
int X<int>::Value = 0;
