Module which implements a newick string parser as a finite state machine which enables it to parse the full Newick specification.
Taken largely from the Ensembl Compara file with the same name (Bio::EnsEMBL::Compara::Graph::NewickParser), this module adapts the parser to work with BioPerl's event handler-based parsing scheme.
This module is used by nhx.pm and newick.pm, and is NOT called directly. Instead, both of those parsing modules extend this module in order to gain access to the main parsing method.
# From newick.pm use base qw(Bio::TreeIO Bio::TreeIO::NewickParser); # in the next_tree method... $self->parse_newick($_);
This module correctly parses the Newick and NHX formats, sending calls to the BioPerl TreeEventHandler when appropriate in order to build and populate the node objects.
User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the Bioperl mailing list. Your participation is much appreciated.
