-
libsemigroups::Congruence::Congruence(congruence_type type, std::shared_ptr<FroidurePinBase> S)¶
Constructs a Congruence over the FroidurePin instance
S
representing a left/right/2-sided congruence according totype
.- Exceptions
Does not throw itself but functions called by this function may throw.
- Complexity
Constant.
Note
The FroidurePinBase pointed to by
S
is not copied.- Parameters
type – whether the congruence is left, right, or 2-sided
S – a shared_ptr to the semigroup over which the congruence is defined.
