larch.NestingTree.add_edge

NestingTree.add_edge(u, v, implied=False, _clear_caches=True, **kwarg)

Add an edge between u and v.

The nodes u and v will be automatically added if they are not already in the graph.

Edge attributes can be specified with keywords.

Parameters:

• u (int) – Nodes should be integer codes. The upstream node u is a nest or the root node. Downsteam node v can be a nest or elemental alternative.

• v (int) – Nodes should be integer codes. The upstream node u is a nest or the root node. Downsteam node v can be a nest or elemental alternative.

• implied (bool, default False) – Implied edges are for connection of otherwise unconnected nests to the root node.

• _clear_caches (bool, default True)

• kwarg (keyword arguments, optional) – Edge data (or labels or objects) can be assigned using keyword arguments.
