Detailed Description

a graph with random edges

Generates a graph with a specified number of vertices, with the density of edges specified by either an exact number of edges or the probability of an edge. You may additionally specify whether to begin with a random tree (which enforces graph connectivity).

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkGraphAlgorithm.

Reimplemented in vtkGeoRandomGraphSource.

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkGraphAlgorithm.

virtual int vtkRandomGraphSource::GetNumberOfVertices ( )

virtual

The number of vertices in the graph.

virtual void vtkRandomGraphSource::SetNumberOfVertices ( int )

virtual

The number of vertices in the graph.

virtual int vtkRandomGraphSource::GetNumberOfEdges ( )

virtual

If UseEdgeProbability is off, creates a graph with the specified number of edges.

Duplicate (parallel) edges are allowed.

virtual void vtkRandomGraphSource::SetNumberOfEdges ( int )

virtual

If UseEdgeProbability is off, creates a graph with the specified number of edges.

Duplicate (parallel) edges are allowed.

virtual double vtkRandomGraphSource::GetEdgeProbability ( )

virtual

If UseEdgeProbability is on, adds an edge with this probability between 0 and 1 for each pair of vertices in the graph.

virtual void vtkRandomGraphSource::SetEdgeProbability ( double )

virtual

If UseEdgeProbability is on, adds an edge with this probability between 0 and 1 for each pair of vertices in the graph.

virtual void vtkRandomGraphSource::SetIncludeEdgeWeights ( bool )

virtual

When set, includes edge weights in an array named "edge_weights".

Defaults to off. Weights are random between 0 and 1.

virtual bool vtkRandomGraphSource::GetIncludeEdgeWeights ( )

virtual

When set, includes edge weights in an array named "edge_weights".

Defaults to off. Weights are random between 0 and 1.

virtual void vtkRandomGraphSource::IncludeEdgeWeightsOn ( )

virtual

When set, includes edge weights in an array named "edge_weights".

Defaults to off. Weights are random between 0 and 1.

virtual void vtkRandomGraphSource::IncludeEdgeWeightsOff ( )

virtual

When set, includes edge weights in an array named "edge_weights".

Defaults to off. Weights are random between 0 and 1.

virtual void vtkRandomGraphSource::SetEdgeWeightArrayName ( const char * )

virtual

The name of the edge weight array.

Default "edge weight".

virtual char* vtkRandomGraphSource::GetEdgeWeightArrayName ( )

virtual

The name of the edge weight array.

Default "edge weight".

virtual void vtkRandomGraphSource::SetDirected ( bool )

virtual

When set, creates a directed graph, as opposed to an undirected graph.

virtual bool vtkRandomGraphSource::GetDirected ( )

virtual

When set, creates a directed graph, as opposed to an undirected graph.

virtual void vtkRandomGraphSource::DirectedOn ( )

virtual

When set, creates a directed graph, as opposed to an undirected graph.

virtual void vtkRandomGraphSource::DirectedOff ( )

virtual

When set, creates a directed graph, as opposed to an undirected graph.
