I have a question about Grasshopper input parameters:
When I get one element I use:
bool GetData<T>(int index, ref T destination);
bool GetDataTree<T>(int index, out GH_Structure<T> tree) where T : IGH_Goo;
bool GetDataList<T>(int index, List<T> list);
In the item case, element is passed as a reference, in the tree case as out.
What happens at the list case?
Can someone show me an example of a C# method how the GetDataList function is written?
I think I am missing some knowledge in basic function principles.
Because the return value is boolean, but somehow the list is passed without ref or out keywords.
