Graph::EdgeIt Class Reference

Detailed Description

This iterator goes through each edge of the 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;
const Invalid INVALID
Invalid iterators.

Constructor & Destructor Documentation

◆ EdgeIt() [1/5]

EdgeIt ( )
inline

EdgeIt ( const EdgeIt & e)
inline

Copy constructor.

◆ EdgeIt() [3/5]

inline

Initializes the iterator to be invalid.

See also
Invalid for more details.

EdgeIt ( const Graph & )
inlineexplicit

Sets the iterator to the first edge of the given graph.

◆ EdgeIt() [5/5]

EdgeIt ( const Graph & ,
