In GATConv, can we make eij as 0, if there is no edge from node i to node j ?

Applications for graphs that are directed, both cyclic and acyclic graphs.

That would correspond to a fully-connected graph, wouldn't it? What is the use-case here?

In particular, I am referring to directed edges. Why would directed edge make it a fully-connected graph ?
