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