 |
|
Hello,
how can I make this:
| Code: |
/* File : example.h */
// Some template definitions
template<class T> T max(T a, T b) { return a>b ? a : b; }
template<class T> class vector {
T *v;
int sz;
public:
vector(int _sz) {
v = new T[_sz];
sz = _sz;
}
T &get(int index) {
return v[index];
}
void set(int index, T &val) {
v[index] = val;
}
};
|
avaible in D?
Best regards |

I would write :
| Code: |
T max(T)(T a, T b)
{
return a>b ? a : b;
}
class Vector(T)
{
private:
T[] v;
public:
this(int sz)
{
v.length = sz;
}
void set(int index, T val)
{
v[index] = val;
}
T get(int index)
{
return v[index];
}
}

Thank you for the code, but I meant more to make a binding to the c++ code so that I can use it under D and to rewrite it.
Is it possible to make a binding to the c++ code? |

| It is possible but only in D2 and it's quite limited. |

D templates have little in common with C++ templates, and it is very unlikely that any sort of reasonable method could be found to express C++ templates in a link-compatible way with D.
This means that the C++ STL, and C++ Boost, likely will never be accessible from D.

clayasaurus already said it: no.
Templates aren't supported. |
