=head1 NAME

Bio::Ontology::TermFactory - Instantiates a new 
Bio::Ontology::TermI (or derived class) through a factory

=head1 SYNOPSIS

    use Bio::Ontology::TermFactory;

    # the default type is Bio::Ontology::Term
    my $factory = Bio::Ontology::TermFactory->new(
                        -type => 'Bio::Ontology::GOterm');
    my $term = $factory->create_object(-name => 'peroxisome',
                                       -ontology => 'Gene Ontology',
                                       -identifier => 'GO:0005777');


=head1 DESCRIPTION

This object will build L<Bio::Ontology::TermI> objects generically.

# Let the code begin...


package Bio::Ontology::TermFactory;

use strict;

use Bio::Root::Root;

use base qw(Bio::Factory::ObjectFactory);

=head2 new

 Title   : new
 Usage   : my $obj = Bio::Ontology::TermFactory->new();
 Function: Builds a new Bio::Ontology::TermFactory object 
 Returns : Bio::Ontology::TermFactory
 Args    : -type => string, name of a Bio::Ontology::TermI derived class.
                    The default is Bio::Ontology::Term.

See L<Bio::Ontology::TermI>, L<Bio::Ontology::Term>.

sub new {
    my($class,@args) = @_;

    my $self = $class->SUPER::new(@args);
  
    # make sure this matches our requirements
    $self->interface("Bio::Ontology::TermI");
    $self->type($self->type() || "Bio::Ontology::Term");

    return $self;
}


=head2 create_object

 Title   : create_object
 Usage   : my $term = $factory->create_object(<named parameters>);
 Function: Instantiates new Bio::Ontology::TermI (or one of its child classes)

           This object allows us to genericize the instantiation of
           Term objects.

 Returns : Bio::Ontology::TermI compliant object
           The return type is configurable using new(-type =>"...").
 Args    : initialization parameters specific to the type of term
           object we want.  Typically 
           -name        => $name
           -identifier  => identifier for the term
           -ontology    => ontology for the term

See L<Bio::Ontology::TermI>.
