Represents an exceptional (alpha, beta) fibre in a Seifert fibred space.
The first parameter alpha must be strictly positive, and the two parameters alpha and beta must be coprime.
Note that we allow regular fibres with alpha = 1, and we do not impose range limits on beta (thus beta may be negative, or it may be larger than alpha). This is to allow more flexibility in routines such as SFSpace::insertFibre().
These objects are small enough to pass by value and swap with std::swap(), with no need for any specialised move operations or swap functions.
- Warning
- In Regina 4.2.1 and earlier, this class was named NExceptionalFibre. The new SFSFibre class was introduced with Regina 4.3, and has changed its behaviour (in particular, the natural ordering of fibres has changed). Code that was written to work with the old NExceptionalFibre class should be looked at closely before being adapted to the new SFSFibre class (i.e., it may require more than just substituting class names).
