 Post subject: overloading "[" operator for newstructs
PostPosted: Wed Mar 19, 2014 5:35 pm 
Hello everyone, I am currently working on a package for handling arrangements of hyperplanes.

I already managed to get the operators "+" and "=" working to my confidence, but I am still struggling with "[".
So I want it to behave the same for our newstruct "arr" (which is basically a list) as it does for lists/ideals.

With
Code:
system("install", "arr" , "[", arrGet ,2);
I managed to get access, i.e. A[2]; returns me the second second hyperplane for an arrangement A.
However I cannot figure out to overload this for assignement, i.e. that A[2] = h; would actually save h as the second hyperplane of my arrangement.

So as far as I know in C one can do this like
Code:
public object this[int i]
{
    get { return InnerList[i]; }
    set { InnerList[i] = value; }
}


Is there a way to do this in Singular, too?
