# tlp::AcyclicTest Class Reference [Graph_test] `#include <AcyclicTest.h>` Inherits tlp::GraphObserver. Inheritance diagram for tlp::AcyclicTest: [legend] Collaboration diagram for tlp::AcyclicTest: [legend] List of all members. ## Detailed Description Class for testing if the graph is acyclic. ## Static Public Member Functions static bool isAcyclic (const Graph *graph) static void makeAcyclic (Graph *graph, std::vector< edge > &reversed, std::vector< tlp::SelfLoops > &selfLoops) static bool acyclicTest (const Graph *, std::vector< edge > *obstructionEdges=0) ## Member Function Documentation
static bool tlp::AcyclicTest::isAcyclic | ( | const Graph * | graph | ) | `[static]`
| returns true if the graph is acyclic, false if not. The result is cached (ie. the next call with the same graph is done in O(1) time)
