cbegin_D_classes

const_d_class_iterator libsemigroups::Konieczny::cbegin_D_classes() const

Returns a const iterator referring to a pointer to the first \(\mathscr{D}\)-class of the semigroup.

This member function does not perform any enumeration of the semigroup; the iterator returned may be invalidated by any call to a non-const member function of the Konieczny class.
