IDableDigraphComponent< BAS > Class Template Reference

Detailed Description

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

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

Member Function Documentation

◆ id() [1/2]

template<typename BAS = BaseDigraphComponent>
int id ( const Node & ) const
inline

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

◆ nodeFromId()

template<typename BAS = BaseDigraphComponent>
Node nodeFromId ( int ) const
inline

This function returns the node by its unique id. If the digraph does not contain a node with the given id, then the result of the function is undefined.

◆ id() [2/2]

template<typename BAS = BaseDigraphComponent>
int id ( const Arc & ) const
inline

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

◆ arcFromId()

template<typename BAS = BaseDigraphComponent>
Arc arcFromId ( int ) const
inline

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

◆ maxNodeId()

template<typename BAS = BaseDigraphComponent>
int maxNodeId ( ) const
inline

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

◆ maxArcId()

template<typename BAS = BaseDigraphComponent>
int maxArcId ( ) const
inline

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