Detailed Description
This class identifies an arc of the digraph. It also serves as a base class of the arc iterators, thus they will convert to this type.

List of all members.
Constructor & Destructor Documentation
- Warning:
- The default constructor sets the iterator to an undefined value.
Initialize the iterator to be invalid.

bool operator== |
( |
Arc |
|
) |
const [inline] |
Two iterators are equal if and only if they point to the same object or both are invalid.
bool operator!= |
( |
Arc |
|
) |
const [inline] |
- See also:
- operator==(Arc n)
bool operator< |

const [inline] |
To allow the use of digraph descriptors as key type in std::map or similar associative container we require this.
- Note:
- This operator only have to define some strict ordering of the items; this order has nothing to do with the iteration ordering of the items.
