Modelica C++ templates

Question

Does Modelica have something equivalent to C++ templates? I would like to build a class that would process an input of type T, but T would be known only when instantiating the class. I tried to pass the type as a parameter but it gives errors.

Answer 1

You can use replaceable types/classes.

model M
  replaceable class C; // = some partial class if you need an interface constrainedby ...
  C c;
end M;

model Test
  M m1(redeclare class C = C1);
  M m2(redeclare class C = C2);
end Test;
