## Public Member Functions

TeGraphNetwork ()
Empty constructor.
TeGraphNetwork (TeLineSet &ls)
Create a graph from TeLineSet; the line size is considered the cost. In this case, graph non-directed.
TeGraphNetwork (TeLineSet &ls, map< string, double > &line_costs)
Create a graph from TeLineSet; the cost is given by the map.
TeGraphNetwork (TeSTElementSet &stos, string &attrName)
Create a network from a set of line objects; the cost is given by the attrName sto property. The graph is non-directed.
TeGraphNetworkoperator= (TeGraphNetwork &other)
Assignment operator.
bool Add (TeLineSet &ls, map< string, double > &line_costs)
Add lineset to graph. Useful specially for directed graphs (lines must be entered in both directions. It has to be tested for existing graphs.
bool minimumPath (TeNode &n1, TeNodeSet &set, vector< double > &dist)
Calculate the minimun path.
bool getNode (int i, TeNode &node)
Get the i-th node.
bool nearestNodePoint (TeCoord2D &p1, int &lindex, TeCoord2D &pinter, double &distance, double tol=0.0)
Get the nearest network node of a specific point (p1)
bool nearestNetworkPoint (TeCoord2D &p1, int &lindex, TeCoord2D &pinter, double &distance, double tol=0.0)
Get the nearest network lines point from a specific point (p1)
TeLineSet getLineSet ()
Get line Set.
map< string, double > getLineCosts ()
Get line costs.
void insertLine (TeLine2D &line, const double &attr)
Insert a new line.
bool breakLineSet (TeNode &node, int i)
Insert a new node.
virtual ~TeGraphNetwork ()
Destructor.

## Protected Attributes

br_stl::Graph< TeNode, double > graph_
Set of nodes and the cost of each edge.
TeLineSet line_set_
Set of geometric representation of edges.
map< string, double > line_cost_
A map to associate each edge (line object_id) to its cost.
