NstEdge

class NstEdge

Directed edge in a graph (see class NstGraph)

Inheritance:

Public Fields
int tag[10]: Multi-purpose tags

Public Methods
virtual NstEdge* clone(int deep = 0): Clones the edge. No recursive cloning available.
void copy(const NstEdge & s, int deep = 0): Copy the edge. No recursive copy available.
void from(NstVertex * const new_from): Changes the tail of the edge.
NstVertex* from(): Returns the tail of the edge.
NstEdge(): Creates an edge with empty head and tail, tags are not initialized.
virtual void print(ostream &s): Output method (used by operator <<).
NstVertex* to(): Returns the head of the edge.
void to(NstVertex * const new_to): Changes the head of the edge.
virtual Nst_Edge_Type type(): Returns the type of edge: here NST_EDGE_BASIC.
virtual ~NstEdge(): virtual destructor

Private Methods
friend ostream& operator << (ostream&, const NstEdge&): Prints the edge.

Documentation

Directed edge in a graph (see class NstGraph). Basic object.
An edge is directed from a vertex (see class NstVertex) called the tail to a vertex called the head.
