BpGraph::Edge Class Reference

Detailed Description

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

Constructor & Destructor Documentation

Edge ( )

inline

Default constructor.

Warning

It sets the object to an undefined value.

Edge ( const Edge &  )

inline

Copy constructor.

Edge ( Invalid  )

inline

Initializes the object to be invalid.

See Also

Invalid for more details.

Member Function Documentation

bool operator== ( Edge  ) const

inline

Equality operator.

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

bool operator!= ( Edge  ) const

inline

Inequality operator.

bool operator< ( Edge  ) const

inline

Artificial ordering operator.

Note

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