Class UniformRandomGraphGenerator
java.lang.Object
org.jgrapht.experimental.UniformRandomGraphGenerator
- All Implemented Interfaces:
- GraphGenerator
public class UniformRandomGraphGenerator
- extends Object
- implements GraphGenerator
UniformRandomGraphGenerator generates a uniform random graph
of any size. A uniform random graph contains edges chosen independently
uniformly at random from the set of all possible edges.

UniformRandomGraphGenerator
public UniformRandomGraphGenerator(int numVertices,
int numEdges)
- Construct a new UniformRandomGraphGenerator.
- Parameters:
numVertices
- number of vertices to be generatednumEdges
- number of edges to be generated
- Throws:
IllegalArgumentException
generateGraph
public void generateGraph(Graph target,
VertexFactory vertexFactory,
Map resultMap)
- Description copied from interface:
GraphGenerator
- Generate a graph structure. The topology of the generated graph is
dependent on the implementation. For graphs in which not all vertices
share the same automorphism equivalence class, the generator may produce
a labeling indicating the roles played by generated elements. This is the
purpose of the resultMap parameter. For example, a generator for a wheel
graph would designate a hub vertex. Role names used as keys in resultMap
should be declared as public static final Strings by implementation
classes.
- Specified by:
generateGraph
in interface GraphGenerator
- Parameters:
target
- receives the generated edges and vertices; if this is
non-empty on entry, the result will be a disconnected graph since
generated elements will not be connected to existing elementsvertexFactory
- called to produce new verticesresultMap
- if non-null, receives implementation-specific mappings
from String roles to graph elements (or collections of graph elements)- See Also:
