Cell type mismatched : Global.LocalStorage.UseFriendship(Monica.CellID) about graphengine

[leoxia]

@PhanDuc Each cell in Graph Engine has a unique cell id. If we want to use the strongly-typed accessor UseFriendship, we have to feed in the id of a Friendship cell.

Let's say Rachel, Monica, and Ross are friends. We can create a Friendship cell as following:

var friendship = new Friendship(new List<long>());
friendship.friends.Add(Rachel.CellID);
friendship.friends.Add(Monica.CellID);
friendship.friends.Add(Ross.CellID);
Global.LocalStorage.SaveFriendship(friendship);

Then, we can use the cell accessor to access the Friendship cell:

using (var f = Global.LocalStorage.UseFriendship(friendship.CellID))
{
    Console.WriteLine("List of cell ids of persons in this frienship:");
    f.friends.ForEach(cellId => Console.WriteLine(cellId));
}

hi PhanDuc,

The entities (and also the accessor) are strongly-typed, which means that you cannot use a Character (a person) object like a Friendship (a kind of hyperedge).

Hint: Try to hack the demo and add an edge from a person to the friendships.

Hi @yatli ,
