Constructor Detail

SelfLoopTool

public SelfLoopTool(PlanarInformation _planar)

Returns a new instance of SelfLoopTool.

Parameters:

_planar - the embedded graph in which the self-loops should be hidden.

Method Detail

hideSelfLoops

public void hideSelfLoops()

Hides all self-loops in a graph.

reinsertSelfLoops

public void reinsertSelfLoops()

Reinserts the formerly hidden self-loops into the embedded graph. Precondition: Edge order must be ok and faces must be calculated in the planar embedding.
