I'm getting the complaint from complier when trying to convert a array of enum to an pointer of int.
在尝试将枚举数组转换为int指针时,我从complier得到了抱怨。
void format(const int *values);
// convert and call format
format(static_cast<const int*>(EnumArray));
// error from compiler
error: invalid static_cast from type 'const EnumArray[15]' to type 'const int*'
Any way to get around it? Thanks!
有办法解决它吗?谢谢!

#1
Seems I can solve it with template. It compiles and runs.
似乎我可以用模板解决它。它编译并运行。
template<typename T>
String8 format(const T *values)
{
//use values as array of int
int v = values[i];
}
//call it
format(EnumArray); // no type needed since it can be deduced
#2
If you exactly know what you are doing, you can use reinterpret_cast
.
如果您确切知道自己在做什么,可以使用reinterpret_cast。
format(reinterpret_cast<const int*>(EnumArray));
