| 25 | The BGL defines several exception classes for reporting errors from |
|---|
| 26 | BGL algorithms. Many of the BGL algorithms place certain requirements |
|---|
| 27 | on the input graph. If these requirements are not met then the |
|---|
| 28 | algorithm can not successfully complete, and instead throws the |
|---|
| 29 | appropriate exception. |
