mgx::util::Insert< vvgraph, do_checks > Class Template Reference

Insert a new vertex on an edge. More...

#include <Insert.hpp>

Detailed Description

template<class vvgraph, bool do_checks = true>
class mgx::util::Insert< vvgraph, do_checks >

Insert a new vertex on an edge.

Parameters
aan existing vertex
ban exsisting vertex
Sthe vv graph to edit

This function creates a new vertex and inserts it between two existing vertices by replacing it into the existing neighbourhoods. If the vertices have no relation or an assymmetric relation, a warning is printed to stderr and an empty vertex is returned.

Example:

vvgraph S;
vertex v1, v2;
S.insert(v1);
S.insert(v2);
S.insertEdge(v1,v2);
S.insertEdge(v2,v1);
Insert<vvgraph> insert;
vertex v = insert(v1, v2, S);

The pre-condition is that edges (v1,v2) and (v2,v1) exist.

The post-condition is that v replaced v2 in the neighborhood of v1 and v1 in the neighborhood of v2, keeping the double connections.
