IDableGraphComponent< BAS > Class Template Reference

Detailed Description

template<typename BAS = BaseGraphComponent>
class lemon::concepts::IDableGraphComponent< BAS >

This class describes the interface of idable undirected graphs. It extends IDableDigraphComponent with the core ID functions of undirected graphs. The ids of the items must be unique and immutable. This concept is part of the Graph concept.

Member Function Documentation

◆ id()

template<typename BAS = BaseGraphComponent>
int id ( const Edge & ) const
inline

This function returns a unique integer id for the given edge.

◆ edgeFromId()

template<typename BAS = BaseGraphComponent>
Edge edgeFromId ( int ) const
inline

This function returns the edge by its unique id. If the graph does not contain an edge with the given id, then the result of the function is undefined.

◆ maxEdgeId()

template<typename BAS = BaseGraphComponent>
int maxEdgeId ( ) const
inline

This function returns an integer greater or equal to the maximum edge id.
