ListEdgeSet< GR > Class Template Reference


Detailed Description

template<typename GR>
class lemon::ListEdgeSet< GR >

This structure can be used to establish another graph over a node set of an existing one. This class uses the same Node type as the underlying graph, and each valid node of the original graph is valid in this arc set, therefore the node objects of the original graph can be used directly with this class. The node handling functions (id handling, observing, and iterators) works equivalently as in the original graph.

This implementation is based on doubly-linked lists, from each node the incident edges make up lists, therefore one edge can be erased in constant time. It also makes possible, that node can be removed from the underlying graph, in this case all edges incident to the given node is erased from the arc set.

Parameters:
GRThe type of the graph which shares its node set with this class. Its interface must conform to the Digraph or Graph concept.

This class fully conforms to the Graph concept.
