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.
