Method Summary

Modifier and Type	Method and Description
List<List<V>>	findSimpleCycles() Finds the simple cycles of the graph. Note that the full algorithm is executed on every call since the graph may have changed between calls.
DirectedGraph<V,E>	getGraph() Returns the graph on which the simple cycle search algorithm is executed by this object.
void	setGraph(DirectedGraph<V,E> graph) Sets the graph on which the simple cycle search algorithm is executed by this object.

Method Detail

getGraph

DirectedGraph<V,E> getGraph()

Returns the graph on which the simple cycle search algorithm is executed by this object.

Returns:

The graph.

setGraph

void setGraph(DirectedGraph<V,E> graph)

Sets the graph on which the simple cycle search algorithm is executed by this object.

Parameters:

graph - the graph.

Throws:

IllegalArgumentException - if the argument is null.

findSimpleCycles

List<List<V>> findSimpleCycles()

Finds the simple cycles of the graph.
Note that the full algorithm is executed on every call since the graph may have changed between calls.

Returns:

The list of all simple cycles. Possibly empty but never null.

Throws:

IllegalArgumentException - if the current graph is null.
