Constructor & Destructor Documentation

Arc

(

)

[inline]

Default constructor.

Warning:

It sets the object to an undefined value.

Arc

(

const Arc &

)

Member Function Documentation

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.

bool operator!=

(

Arc

)

const [inline]

Inequality 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.
