Node Parsing stat

Appendix C: Node Parsing and stat

When parsing nodes, Natto::MeCabNode will have a stat (status) value per the following:

• 0 - normal node defined in the dictionary
• 1 - unknown node not defined in the dictionary
• 3 - virtual node representing the end of a sentence

An example:

nm = Natto::MeCab.new
nm.parse('ブルザエモンはいったい何者だ？') {|p|puts "#{p.surface}, #{p.stat}"}

ブルザエモン, 1  # this noun is made-up, you won't find this in any dictionary!
は, 0              
いったい, 0
何者, 0
だ, 0
？, 0
, 3            # end of sentence
