=head1 NAME

Bio::Tools::Prediction::Gene - a predicted gene structure feature

=head1 SYNOPSIS

  #See documentation of methods.

=head1 DESCRIPTION

A feature representing a predicted gene structure. This class actually
inherits off Bio::SeqFeature::Gene::Transcript and therefore has all that
functionality, plus a few methods supporting predicted sequence features,
like a predicted CDS and a predicted translation.

Exons held by an instance of this class will usually be instances of
Bio::Tools::Prediction::Exon, although they do not have to be. Refer to the
documentation of the class that produced the instance.

Normally, you will not want to create an instance of this class yourself.
Instead, classes representing the results of gene structure prediction
programs will do that.

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

package Bio::Tools::Prediction::Gene;
use vars qw(@ISA);
use strict;

use Bio::SeqFeature::Gene::Transcript;


@ISA = qw(Bio::SeqFeature::Gene::Transcript);

sub new {
    my($class,@args) = @_;
    
    my $self = $class->SUPER::new(@args);

    my ($primary,$ptag) = $self->_rearrange([qw(PRIMARY PRIMARY_TAG)],@args);

=head2 predicted_cds

 Title   : predicted_cds
 Usage   : $predicted_cds_dna = $gene->predicted_cds();
           $gene->predicted_cds($predicted_cds_dna);
 Function: Get/Set the CDS (coding sequence) as predicted by a program.

           This method is independent of an attached_seq. There is no
           guarantee whatsoever that the returned CDS has anything to do
           (e.g., matches) with the sequence covered by the exons as annotated
           through this object.

 Example :
 Returns : A Bio::PrimarySeqI implementing object holding the DNA sequence
           defined as coding by a prediction of a program.
 Args    : On set, a Bio::PrimarySeqI implementing object holding the DNA 
           sequence defined as coding by a prediction of a program.

=cut

sub predicted_cds {
    my ($self, $cds) = @_;

    if(defined($cds)) {
	$self->{'_predicted_cds'} = $cds;
    }
    return $self->{'_predicted_cds'};
}

=head2 predicted_protein

 Title   : predicted_protein
 Usage   : $predicted_protein_seq = $gene->predicted_protein();
           $gene->predicted_protein($predicted_protein_seq);
 Function: Get/Set the protein translation as predicted by a program.

           This method is independent of an attached_seq. There is no
           guarantee whatsoever that the returned translation has anything to
           do with the sequence covered by the exons as annotated
           through this object, or the sequence returned by predicted_cds(),
           although it should usually be just the standard translation.

 Example :
 Returns : A Bio::PrimarySeqI implementing object holding the protein 
           translation as predicted by a program.
 Args    : On set, a Bio::PrimarySeqI implementing object holding the protein 
           translation as predicted by a program.

=cut

sub predicted_protein {
    my ($self, $aa) = @_;

    if(defined($aa)) {
	$self->{'_predicted_aa'} = $aa;
    }
    return $self->{'_predicted_aa'};
