Graph::Arc Class Reference

Detailed Description

This class identifies a directed arc of the graph. It also serves as a base class of the arc iterators, thus they will convert to this type.

Constructor & Destructor Documentation

◆ Arc() [1/3]

Arc ( )
inline

Default constructor.

Warning
It sets the object to an undefined value.

◆ Arc() [2/3]

Arc ( const Arc & )
inline

Copy constructor.

◆ Arc() [3/3]

Arc ( Invalid )
inline

Initializes the object to be invalid.

See also
Invalid for more details.

Member Function Documentation

◆ operator==()

bool operator== ( Arc ) const
inline

Equality operator.

Two iterators are equal if and only if they point to the same object or both are INVALID.

◆ operator!=()

bool operator!= ( Arc ) const
inline

Inequality operator.

◆ operator<()

bool operator< ( Arc ) const
inline

Artificial ordering operator.

Note
This operator only has to define some strict ordering of the arcs; this order has nothing to do with the iteration ordering of the arcs.

◆ operator Edge()

operator Edge ( ) const
inline

Converison to Edge.
