getSolver()

static

isClusterPlanar()

bool ogdf::HananiTutteCPlanarity::isClusterPlanar ( const ClusterGraph &  CG )

inlineoverridevirtual

Returns true, if CG is cluster-planar, false otherwise.

Reimplemented from ogdf::ClusterPlanarityModule.

Definition at line 103 of file HananiTutteCPlanarity.h.

isClusterPlanarDestructive()

bool ogdf::HananiTutteCPlanarity::isClusterPlanarDestructive ( ClusterGraph &  CG, Graph &  G  )

inlineoverridevirtual

Returns true, if CG is cluster-planar, false otherwise. In it is non-cluster-planar, the (Cluster)Graph may be arbitrarily changed after the call.

This variant may be slightly faster than the default isClusterPlanar

Implements ogdf::ClusterPlanarityModule.
