    public interface IBiDirectionalGraphDataSource<V>
    extends IGraphDataSource<V>
    A bi-directional graph data source supports all operations that an IGraphDataSource does, but it also makes it possible to query the incoming edges of nodes, not only the outgoing edges.

        IMemoryView<V> getSourceNodes​(V target)
        Returns the source nodes for the given target node. The returned data structure is an IMultiset because of potential parallel edges in the graph data source. The method must not return null.
        Parameters:
        target - the target node
        Returns:
        the multiset of source nodes
