| bool | fo.operator() ( Kernel::Direction_2 d, Kernel::Direction_2 d1, Kernel::Direction_2 d2) | |
| returns true iff d is not equal to d1, and while rotating counterclockwise starting at d1, d is reached strictly before d2 is reached. Note that true is returned if d1 == d2, unless also d == d1. | ||
