Objects from the Class
Objects can be created by calls of the form new("directedEdge", ...)
which admit short-hands of the form d(...) and r(...).Slots
.Data:- Object of class
"list"
storing strictly positive numbers that refer to a given "vertexSet" object
Extends
Class "edge", directly.
Class "list", from data part.
Class "vector", by class "list".Methods
- initialize
signature(.Object = "directedEdge"):
constructs a directed edge from a list of strictly positive integers- show
signature(object = "directedEdge"):
displays a directed edge as an ordered sequence of undirected edges joined by arrows (using numeric codes)- showRel
signature(object = "directedEdge",code="vertexSet"):
displays a directed edge as an ordered sequence of undirected edges joined by arrows (using character names- areTheSame
signature(x = "directedEdge", y = "directedEdge"):
x and y are the same directed edge if they are the same ordered sequence of undirected edges- [
signature(x = "directedEdge"): extracts a directed edge- [[
signature(x = "directedEdge"): extracts an undirected edge- card
signature(object= "directedEdge"): counts all vertices in a directed edge- coerce
signature(from = "vector", to = "directedEdge"): constructs a directed edge from vector input- coerce
signature(from = "undirectedEdge", to = "directedEdge"): directs an undirected edge- maxId
signature(x="directedEdge"): gets the maximum numeric identifier of a directed edge- recode
signature(object="directedEdge",src = "vertexSet", dst = "vertexSet"):
recodes a directed edge by making its numbers refer to another "vertexSet" object
Warning
The constructor will try to handle any vector input
by silently transforming it into a list of strictly positive integers.
