so, where can I find it?
What I want is loop over a user-defined class/struct. In case
of C#, I just implement the IEnumerable and the GetEnumerator()
methods that's called by the foreach() construct together with
the yield keyword I "feed" the loop until the moveNext()
returns false (no next element). The think I've linked has some
C# code example.
Something like this:
struct MyStruct
{
// proper methods/proeperties called by foreach() to iterate
// over the array
int[] myarr;
int = 0;
int getNext() { return myarr[i]; }
bool hasNext() { return i == myarr.length; }
}
MyStruct s;
foreach(MyStruct x; s)
{
}
Is this possible?
use opApply.
