Method Summary

Modifier and Type	Method and Description
void	createEdges(Graph<VV,EE> targetGraph, Map<Integer,VV> orderToVertexMap, int numberOfEdges, Random randomizer) Two different calls to the createEdges() with the same parameters must result in the generation of the same.
boolean	isNumberOfEdgesValid(Graph<VV,EE> targetGraph, int numberOfEdges) Checks if the graph can contain the givven numberOfEdges according to the graph type restrictions.

Method Detail

createEdges

void createEdges(Graph<VV,EE> targetGraph,
                 Map<Integer,VV> orderToVertexMap,
                 int numberOfEdges,
                 Random randomizer)

Two different calls to the createEdges() with the same parameters must result in the generation of the same. But if the randomizer is different, it should, usually, create different edge topology.

Parameters:

targetGraph - - guranteed to start with zero edges.

orderToVertexMap - - key=Integer of vertex order . between zero to numOfVertexes (exclusive). value = vertex from the graph. unique.

numberOfEdges - - to create in the graph

randomizer -

isNumberOfEdgesValid

boolean isNumberOfEdgesValid(Graph<VV,EE> targetGraph,
                             int numberOfEdges)

Checks if the graph can contain the givven numberOfEdges according to the graph type restrictions. For example:

1. #V means number of vertexes in graph
2. a Simple Graph, can have max of #V*(#V-1)/2 edges. etc

Parameters:

targetGraph - guranteed to start with zero edges.

numberOfEdges -
