Graph::EdgeIt Class Reference


Detailed Description

This iterator goes through each edge of a graph. Its usage is quite simple, for example you can count the number of edges in a graph g of type Graph as follows:

          int count=0;
          for(Graph::EdgeIt e(g); e!=INVALID; ++e) ++count;

 EdgeIt ()
 Default constructor.
 EdgeIt (const EdgeIt &e)
 EdgeIt (Invalid)
 EdgeIt (const Graph &)
 EdgeIt (const Graph &, const Edge &)
 Edge -> EdgeIt conversion.
EdgeItoperator++ ()
 Next edge.

Constructor & Destructor Documentation

EdgeIt ( ) [inline]
Warning:
The default constructor sets the iterator to an undefined value.
EdgeIt ( const EdgeIt e) [inline]

Copy constructor.

EdgeIt ( Invalid  ) [inline]

Initialize the iterator to be invalid.

EdgeIt ( const Graph ) [inline]

This constructor sets the iterator to the first edge.

EdgeIt ( const Graph ,
const Edge  
) [inline]

Sets the iterator to the value of the trivial iterator. This feature necessitates that each time we iterate the edge-set, the iteration order is the same.


Member Function Documentation

EdgeIt& operator++ ( ) [inline]

Assign the iterator to the next edge.
