graphicle.select.vertex_descendants(adj: AdjacencyList, vertex: int) → MaskArray[source]

Returns a MaskArray to select edges which descend from a given interaction vertex.

New in version 0.1.0.

Changed in version 0.2.7: In the edge case of no descendants, now returns a mask with identifying edges whose source is the vertex, rather than raising an unhandled IndexError.

Parameters:
adj : AdjacencyList

Topological structure of the graph.

vertex : int

The vertex id from which the descending edges are identified.

Returns:

Boolean mask over the graphicle objects associated with the passed AdjacencyList.

Return type:

MaskArray
