Constructor and Description 

JohnsonSimpleCycles()
Create a simple cycle finder with an unspecified graph.

JohnsonSimpleCycles(Graph<V,E> graph)
Create a simple cycle finder for the specified graph.

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. 
Graph<V,E> 
getGraph()
Returns the graph on which the simple cycle search algorithm is executed by this object.

void 
setGraph(Graph<V,E> graph)
Sets the graph on which the simple cycle search algorithm is executed by this object.
