BpGraph::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 BpGraph as follows:

int count=0;
for(BpGraph::EdgeIt e(g); e!=INVALID; ++e) ++count;
const Invalid INVALID
Invalid iterators.
Definition: base.cc:32
Iterator class for the edges.
Definition: bpgraph.h:364

Constructor & Destructor Documentation

◆ EdgeIt() [1/5]

EdgeIt ( )
inline

Default constructor.

Warning
It sets the iterator to an undefined value.

◆ EdgeIt() [2/5]

EdgeIt ( const EdgeIt e)
inline

Copy constructor.

◆ EdgeIt() [3/5]

EdgeIt ( Invalid  )
inline

Initializes the iterator to be invalid.

See also
Invalid for more details.

◆ EdgeIt() [4/5]

EdgeIt ( const BpGraph )
inlineexplicit

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

◆ EdgeIt() [5/5]

EdgeIt ( const BpGraph ,
const Edge  
)
inline

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

Member Function Documentation

◆ operator++()

EdgeIt & operator++ ( )
inline

Assign the iterator to the next edge.
