Package com.aoindustries.util.graph

Class TopologicalSorter<V,Ex extends Exception>

java.lang.Object

com.aoindustries.util.graph.TopologicalSorter<V,Ex>

Type Parameters:

Ex - An arbitrary exception type that may be thrown

All Implemented Interfaces:

GraphSorter<V,Ex>

public class TopologicalSorter<V,Ex extends Exception>
extends Object
implements GraphSorter<V,Ex>

Performs a topological sort of all the vertices in the provided symmetric multi graph. If forward, objects with no edges directed out are first. If backward, objects with no edges directed in are first.
