IterableDigraphComponent< BAS > Class Template Reference

Detailed Description

template<typename BAS = BaseDigraphComponent>
class lemon::concepts::IterableDigraphComponent< BAS >

This class describes the interface of iterable directed graphs. It extends BaseDigraphComponent with the core iterable interface. This concept is part of the Digraph concept.

Class Based Iteration
This interface provides iterator classes for digraph items.
typedef GraphItemIt< Digraph, Node >	NodeIt
typedef GraphItemIt< Digraph, Arc >	ArcIt
typedef GraphIncIt< Digraph, Arc, Node, 'i'>	InArcIt
	This iterator goes trough the incoming arcs of a node.
typedef GraphIncIt< Digraph, Arc, Node, 'o'>	OutArcIt
	This iterator goes trough the outgoing arcs of a node.
Node	baseNode (const InArcIt &) const
	The base node of the iterator.
Node	runningNode (const InArcIt &) const
	The running node of the iterator.
Node	baseNode (const OutArcIt &) const
	The base node of the iterator.
Node	runningNode (const OutArcIt &) const
	The running node of the iterator.

Public Member Functions
Base Iteration
This interface provides functions for iteration on digraph items.
void	first (Node &) const
	Return the first node.
void	next (Node &) const
	Return the next node.
void	first (Arc &) const
	Return the first arc.
void	next (Arc &) const
	Return the next arc.
void	firstIn (Arc &, const Node &) const
	Return the first arc incoming to the given node.
void	nextIn (Arc &) const
	Return the next arc incoming to the given node.
void	firstOut (Arc &, const Node &) const
	Return the first arc outgoing form the given node.
void	nextOut (Arc &) const

Node baseNode ( const OutArcIt &  ) const

inline

This function gives back the base node of the iterator. It is always the source node of the pointed arc.

Node runningNode ( const OutArcIt &  ) const

inline

This function gives back the running node of the iterator. It is always the target node of the pointed arc.
