BaseGraphComponent Class Reference

---

Detailed Description

This class describes the base interface of undirected graph types. All graph concepts have to conform to this class. It extends the interface of BaseDigraphComponent with an Edge type and functions to get the end nodes of edges, to convert from arcs to edges and to get both direction of edges.

Member Function Documentation

Node u

(

const Edge &

)

const [inline]

This function returns one end node of an edge.

Node v

(

const Edge &

)

const [inline]

This function returns the other end node of an edge.

Arc direct	(	const Edge &	,
		bool
	)		const [inline]

This function returns a directed arc from its direction and the represented edge.

Arc direct	(	const Edge &	,
		const Node &
	)		const [inline]

This function returns a directed arc from its source node and the represented edge.

bool direction

(

const Arc &

)

const [inline]

Returns the direction of the arc. Each arc represents an edge with a direction. It gives back the direction.

Arc oppositeArc

(

const Arc &

)

const [inline]

This function returns the opposite arc, i.e. the arc representing the same edge and has opposite direction.
