Edge () | |
Default constructor. | |
Edge (const Edge &) | |
Edge (Invalid) | |
bool | operator== (Edge) const |
Equality operator. | |
bool | operator!= (Edge) const |

Edge | ( | ) | [inline] |
bool operator== | ( | Edge | ) | const [inline] |
Two iterators are equal if and only if they point to the same object or both are invalid.
bool operator!= | ( | Edge | ) | const [inline] |
bool operator< | ( | Edge | ) | const [inline] |
To allow the use of graph descriptors as key type in std::map or similar associative container we require this.
