## Detailed Description

### template<typename Cost> class ogdf::GlueMap< Cost >

This is a helper class to make the glueing of two edges simpler.

Definition at line 371 of file NonPlanarCore.h.

## ◆ GlueMap()

template<typename Cost >
 ogdf::GlueMap< Cost >::GlueMap ( edge eWinner, edge eLoser, NonPlanarCore< Cost > & npc )

A GlueMap is created from an NonPlanarCore and two core edges that ought to be glued together.

It holds many mappings, mostly to the original graph of the core.

Parameters
 eWinner This edge gets extended. eLoser This edge gets deleted in the end and everything it represents is transferred to eWinner. npc The NonPlanarCore all of this exists in.

Definition at line 1208 of file NonPlanarCore.h.

## ◆ getLoserGraph()

template<typename Cost >
 const Graph& ogdf::GlueMap< Cost >::getLoserGraph ( ) const
inline

Getter for m_gLoser.

Returns
the graph that loses this glueing

Definition at line 424 of file NonPlanarCore.h.

## ◆ getWinnerNodeOfLoserNode()

template<typename Cost >
 node ogdf::GlueMap< Cost >::getWinnerNodeOfLoserNode ( node v ) const
inline

Getter for m_mapV_l2w.

Parameters
 v the loser node
Returns
the winner node

Definition at line 416 of file NonPlanarCore.h.

## ◆ mapLoserToNewWinnerEdge()

template<typename Cost >
 void ogdf::GlueMap< Cost >::mapLoserToNewWinnerEdge ( edge eInLoser )

A mapping from the eInLoser graph to a new edge in the winner graph is created.

Definition at line 1244 of file NonPlanarCore.h.

## ◆ mapLoserToNewWinnerNode()

template<typename Cost >
 void ogdf::GlueMap< Cost >::mapLoserToNewWinnerNode ( node vInLoser )

A mapping from the vInLoser to a new node in the winner graph is created.

Definition at line 1257 of file NonPlanarCore.h.

## ◆ mapLoserToWinnerNode()

template<typename Cost >
 void ogdf::GlueMap< Cost >::mapLoserToWinnerNode ( node vInLoser, node vInWinner )

A mapping from the vInLoser to the vInWinner is created.

Definition at line 1251 of file NonPlanarCore.h.

## ◆ reorder()

template<typename Cost >
 void ogdf::GlueMap< Cost >::reorder ( node vLoser, bool sameDirection, bool isTNodeOfPNode )

This method reorders the adjacency order of vLoser's counterpart in the winner graph according to the AdjOrder of vLoser in the loser graph.

Parameters
 vLoser the node in question sameDirection false iff this method is called while handling a P Node, for which the edges are not in the same direction. isTNodeOfPNode true iff vLoser is the target node of the loser graph and the glueing process is done on a P Node.
