AlterableGraphComponent< BAS > Class Template Reference

Detailed Description

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

This class describes the interface of alterable undirected graphs. It extends AlterableDigraphComponent with the alteration notifier interface of undirected graphs. It implements an observer-notifier pattern for the edges. More obsevers can be registered into the notifier and whenever an alteration occured in the graph all the observers will be notified about it.
