I am trying to use the answer of a preceding question to implement a small graph library. The idea is to consider graphs as colections, where vertices wrap collection elements. I would like to use abstract types to represent Vertex and Edge types (because of type safety) and I want to use type parameters to represent the type of the col...
In what situations should abstract types be preferred over type parameters? ...
