Detailed Description

Booth-Lueker planarity test.

This class implements the linear-time planarity test proposed by Booth and Luecker, based on PQ-trees.
This class is deprecated! You will usually want to use the more modern/faster/versatile linear-time planarity test by Boyer and Myrvold instead, implemented in the class BoyerMyrvold. Generally, it is suggested to use the direct function calls isPlanar and planarEmbed in extended_graph_alg.h (which in turn use BoyerMyrvold).

Member Function Documentation

doEmbed()

bool ogdf::BoothLueker::doEmbed ( Graph &  G, NodeArray< int > &  numbering, EdgeArray< edge > &  backTableEdges, EdgeArray< edge > &  forwardTableEdges  )

private

Performs a planarity test on a biconnected component of G and embedds it planar.

numbering contains an st-numbering of the component.

doTest()

bool ogdf::BoothLueker::doTest ( Graph &  G, NodeArray< int > &  numbering  )

private

Performs a planarity test on a biconnected component of G.

numbering contains an st-numbering of the component.

entireEmbed()

void ogdf::BoothLueker::entireEmbed ( Graph &  G, NodeArray< SListPure< adjEntry > > &  entireEmbedding, NodeArray< SListIterator< adjEntry > > &  adjMarker, NodeArray< bool > &  mark, node  v  )

private

isPlanar()

virtual bool ogdf::BoothLueker::isPlanar ( const Graph &  G )

overridevirtual

Returns true, if G is planar, false otherwise.

Implements ogdf::PlanarityModule.

isPlanarDestructive()

virtual bool ogdf::BoothLueker::isPlanarDestructive ( Graph &  G )

overridevirtual

Returns true, if G is planar, false otherwise.

Implements ogdf::PlanarityModule.

planarEmbed()

virtual bool ogdf::BoothLueker::planarEmbed ( Graph &  G )

inlineoverridevirtual

Returns true, if G is planar, false otherwise. If true, G contains a planar embedding.

Implements ogdf::PlanarityModule.

Definition at line 65 of file BoothLueker.h.

planarEmbedPlanarGraph()

virtual bool ogdf::BoothLueker::planarEmbedPlanarGraph ( Graph &  G )

inlineoverridevirtual

Returns true, if G is planar, false otherwise. If true, G contains a planar embedding.

For BoothLueker, this procedure is exactly the same as planarEmbed. (See PlanarityModule or BoyerMyrvold for the rationale of this function's existence.

Implements ogdf::PlanarityModule.

Definition at line 72 of file BoothLueker.h.

preparation()

bool ogdf::BoothLueker::preparation ( Graph &  G, bool  embed  )

private

Prepares the planarity test and the planar embedding.

prepareParallelEdges()

void ogdf::BoothLueker::prepareParallelEdges ( Graph &  G )

private
