BpGraph::NodeIt Class Reference

Detailed Description

This iterator goes through each node of the graph. Its usage is quite simple, for example, you can count the number of nodes in a graph g of type BpGraph like this:

int count=0;
for (BpGraph::NodeIt n(g); n!=INVALID; ++n) ++count;

Constructor & Destructor Documentation

◆ NodeIt() [1/5]

NodeIt ( )
inline

Default constructor.

Warning
It sets the iterator to an undefined value.

◆ NodeIt() [2/5]

NodeIt ( const NodeIt n)
inline

Copy constructor.

◆ NodeIt() [3/5]

NodeIt ( Invalid  )
inline

Initializes the iterator to be invalid.

See also
Invalid for more details.

◆ NodeIt() [4/5]

NodeIt ( const BpGraph )
inlineexplicit

Sets the iterator to the first node of the given digraph.

◆ NodeIt() [5/5]

NodeIt ( const BpGraph ,
const Node  
)
inline

Sets the iterator to the given node of the given digraph.

Member Function Documentation

◆ operator++()

NodeIt& operator++ ( )
inline

Assign the iterator to the next node.
