Class VertexId

java.lang.Object

io.improbable.keanu.vertices.VertexId

All Implemented Interfaces:

VariableReference, java.lang.Comparable<VertexId>

public class VertexId
extends java.lang.Object
implements java.lang.Comparable<VertexId>, VariableReference

An object representing the ID value of a vertex. IDs are assigned in such a way that a Lexicographic ordering of all nodes based on their ID value is a valid topological ordering of the graph made up by those vertices. Ids also encapsulate the notion of "Depth". When we have graphs within graphs, the depth tells us at what level the graph exists - ie depth 1 is the outermost graph, depth 2 is a graph within a graph etc.
