inline void libsemigroups::Action::add_generator(element_type gen)¶
Add a generator to the action.
An Action instance represents the action of the semigroup generated by the elements added via this member function.
- Complexity
At most linear in the size() of the action.
- Parameters
gen – the generator to add.
- Throws
(None) – This function guarantees not to throw a
LibsemigroupsException
.- Returns
(None)
-
inline void libsemigroups::Action::add_seed(const_reference_point_type seed)¶
Add a seed to the action.
A seed is just a starting point for the action, it will belong to the action, as will every point that can be obtained from the seed by acting with the generators of the action.
- Complexity
At most linear in the size() of the action.
- Parameters
seed – the seed to add.
- Throws
(None) – This function guarantees not to throw a
LibsemigroupsException
.- Returns
(None)
-
inline void libsemigroups::Action::reserve(size_t val)¶
Increase the capacity to a value that is greater or equal to
val
.- Parameters
val – new capacity of an action instance.
- Throws
std::length_error – if
val
is too large.std::bad_alloc – or any exception thrown by the allocators of private data members.
- Returns
(None)
