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.
