Overview

Mapper class employing the depth-locus node expansion strategy: 


  1. Create the list L of the all unresolved nodes (nonterminal symbols ready for the expansion).
  2. Select only the nodes with the maximal depth from the list L and name it M.
  3. Take the locus codon and use it as the index i on the list M.
  4. Select the node N=M[i] from the list M (and the corresponding nonterminal symbol S).
  5. Take the subsequent (allele) codon of the genome and use it for selection of rule Alternative Mapper::RuleAlt of grammar[S]
  6. Expand the symbol S. 
  7. Repeat from the step 1 until the termination condition (see Mapper::Base) is met.
