Instance methods

add_candidate_seed_parse_tree(candidate_seed_parse_tree)

Sets the seed_parse_tree field to the longest match parse tree between the existing value of the seed_parse_tree field and the supplied candidate_seed_parse_tree. Returns the longest candidate seed parse tree observed (including candidate_seed_parse_tree)
