This is essentially a very thin derivation of the dagflat parser. =head1 FEEDBACK =head2 Mailing Lists 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 lists Your participation is much appreciated. bioperl-l@bioperl.org - General discussion http://bio.perl.org/MailList.html - About the mailing lists =head2 Reporting Bugs report bugs to the Bioperl bug tracking system to help us keep track the bugs and their resolution.

Internal methods are usually preceded with a _ =cut # Let the code begin... package Bio::OntologyIO::goflat; use vars qw( @ISA ); use strict; use Bio::Ontology::TermFactory; use Bio::OntologyIO::dagflat; use constant TRUE => 1; use constant FALSE => 0; @ISA = qw( Bio::OntologyIO::dagflat ); =head2 new Title : new Usage : $parser = Bio::OntologyIO->new( -format => "go", -defs_file => "/path/to/GO.defs", -files => ["/path/to/component.ontology", "/path/to/function.ontology", "/path/to/process.ontology"] ); Function: Creates a new goflat parser. Returns : A new goflat parser object, implementing L<Bio::OntologyIO>. Args : -defs_file => the name of the file holding the term definitions -files => a single ontology flat file holding the term relationships, or an array ref holding the file names (for GO, there will usually be 3 files: component.ontology, function.ontology, process.ontology) -file => if there is only a single flat file, it may also be specified via the -file parameter -ontology_name => the name of the ontology; if not specified the parser will auto-discover it by using the term that starts with a '$', and converting underscores to spaces -engine => the Bio::Ontology::OntologyEngineI object to be reused (will be created otherwise); note that every Bio::Ontology::OntologyI will qualify as well since that one inherits from the former. =cut # in reality, we let OntologyIO::new do the instantiation, and override # _initialize for all initialization work sub _initialize { my ($self, @args) = @_; $self->SUPER::_initialize( @args ); # default term object factory $self->term_factory(Bio::Ontology::TermFactory->new( -type => "Bio::Ontology::GOterm")) unless $self->term_factory(); } # _initialize 1;
