       LayeredMarginal (Marginal &&m, int tabSize=1000, int hashSize=1000)
           Move constructor: specializes the Marginal class.

       bool extend (double new_threshold, bool do_sort=true)
           Extend the set of computed subisotopologues to those above the new threshold.
       double get_lProb (int idx) const
           get the log-probability of the idx-th subisotopologue, see details in

Constructor & Destructor Documentation

   IsoSpec::LayeredMarginal::LayeredMarginal (Marginal && m, int tabSize = 1000, int hashSize =
       1000)
       Move constructor: specializes the Marginal class.

       Parameters
           tabSize The size of the table used to store configurations in the allocator.
           hashSize The size of the hash table used to store visited subisotopologues.

Member Function Documentation

   bool IsoSpec::LayeredMarginal::extend (double new_threshold, bool do_sort = true)
       Extend the set of computed subisotopologues to those above the new threshold.

       Parameters
           new_threshold The new log-probability limiting the subisotopologues from below.

       Returns
           Returns false, if there are no fringe-subisotopologues (subisotopologues that were
           neighbours of the previously calculated subisotopologues, with log-probability below
           the previous threshold).
