public class FullGenerator
extends BaseGenerator

Full graph generator.

Probably not very useful, still sometimes needed. This generator creates fully connected graphs of any size. Calling begin() put one unique node in the graph, then nextEvents() will add a new node each time it is called.

This generator has the ability to add randomly chosen numerical values on arbitrary attributes on edges or nodes of the graph, and to randomly choose a direction for edges.

A list of attributes can be given for nodes and edges. In this case each new node or edge added will have this attribute and the value will be a randomly chosen number. The range in which these numbers are chosen can be specified.

By default, edges are not oriented. It is possible to ask orientation, in which case the direction is chosen randomly.

Constructor Detail

FullGenerator

public FullGenerator()

New full graph generator. By default no attributes are added to nodes and edges, and edges are not directed.

FullGenerator

public FullGenerator(boolean directed,
             boolean randomlyDirectedEdges)

New full graph generator.

Parameters:

directed - Are edge directed?

randomlyDirectedEdges - randomly direct generated edges.

FullGenerator

public FullGenerator(boolean directed,
             boolean randomlyDirectedEdges,
             String nodeAttribute,
             String edgeAttribute)

New full graph generator.

Parameters:

directed - Are edge directed?.

randomlyDirectedEdges - randomly direct generated edges.

nodeAttribute - put an attribute by that name on each node with a random numeric value.

edgeAttribute - put an attribute by that name on each edge with a random numeric value.

Method Detail

begin

public void begin()

Begin the generator by adding a node.

See Also:

Generator.begin()

nextEvents

public boolean nextEvents()

Add a new node and connect it with all others.

Returns:

true while there are elements to add to the graph.
