edgegraph.builder.explicit.link_directed(v1, v2, dontdup=False)

Create a DirectedEdge between the two vertices.

This function instantiates a new DirectedEdge class such that the given v1 is the “from” vertex and the given v2 is the “to” vertex.

Parameters:

• v1 (Vertex) – The origin end of the link.

• v2 (Vertex) – The destination end of the link.

• dontdup (bool) – If set to True, performs a check for any already-existing links between v1 and v2. If any are found (of any type, directed or undirected), no new link is created, but the already-existing one is returned silently.
