| 20 | <P> | |
| 21 | The BGL defines several exception classes for reporting errors from | |
| 22 | BGL algorithms. Many of the BGL algorithms place certain requirements | |
| 23 | on the input graph. If these requirements are not met then the | |
| 24 | algorithm can not successfully complete, and instead throws the | |
| 25 | appropriate exception. | |
| 26 | </P> | |
