public abstract class DFSFinishTimeIterator<T> extends Stack<T> implements Iterator<T>
This class implements depth-first search over aGraph
, return an enumeration of the nodes of the graph in order of increasing finishing time. This class follows the outNodes of the graph nodes to define the graph, but this behavior can be changed by overriding the getConnected method.- See Also:
