Detailed Description

template<typename K, typename E2 = K>
class bridges::datastructure::Edge< K, E2 >

This helper class is used by the graph classes - GraphAdjList , GraphAdjMatrix - to keep track of edge information.

This class is used to assign a visual connection between two Elements in the Bridges Visualization.

Bridges will represent these as arrows between two Elements. The starting Element of the arrow will be referred to as the source Element and the ending Element of the arrow will be referred to as the terminating Element.

Constructor & Destructor Documentation

Edge()

template<typename K , typename E2 = K>

bridges::datastructure::Edge< K, E2 >::Edge ( const K &  from, const K &  to, LinkVisualizer *  lv, const E2 &  data = E2()  )

inline

Constructs an edge with the given destination vertex, and edge data.

This constructor is not meant to be used by the Bridges user. If an argument is not given its default is used.

Parameters

from	source vertex
to	destination vertex
lv	LinkVisualizer storing the styling information for the edge
data	edge data
