Constructor Details

#initialize(*args) ⇒ Edge

d: Create an edge with a name and two vertices a: Check if a string is passed, otherwise, the next two must be the vertices t: constant p: name if we want to name our edge, otherwise it’ll be “”

The next two args are the two vertices that this edge connects

r: Edge object

Instance Method Details

#is_coincident?(e) ⇒ Boolean

d: Check if two edges are covering the same vertices. a: Compare the object_id, by extracting them and sorting them. t: constant p: Edge e is the comparing edge r: true or false depending on coincident

Returns:

  • (Boolean)
