=head1 NAME
Bio::SeqFeature::Gene::ExonI - Interface for a feature representing an exon
=head1 SYNOPSIS
See documentation of methods.
=head1 DESCRIPTION
A feature representing an exon. An exon in this definition is
transcribed and at least for one particular transcript not spliced out
of the pre-mRNA. However, it does not necessarily code for amino acid.

=head1 APPENDIX
The rest of the documentation details each of the object methods.
Internal methods are usually preceded with a _
=cut
# Let the code begin...
package Bio::SeqFeature::Gene::ExonI;
use vars qw(@ISA);
use strict;
use Carp;
use Bio::SeqFeatureI;
@ISA = qw(Bio::SeqFeatureI);
=head2 is_coding
Title : is_coding
Usage : if($exon->is_coding()) {
# do something
}
Function: Whether or not the exon codes for amino acid.
Returns : TRUE if the object represents a feature translated into protein,
and FALSE otherwise.
Args :
=cut
sub is_coding {
my ($self) = @_;
$self->throw_not_implemented();
}
=head2 cds
Title : cds()
Usage : $cds = $exon->cds();
Function: Get the coding sequence of the exon as a sequence object.
The returned sequence object must be in frame 0, i.e., the first
base starts a codon.
An implementation may return undef, indicating that a coding
sequence does not exist, e.g. for a UTR (untranslated region).
Returns : A L<Bio::PrimarySeqI> implementing object.
Args :
=cut
sub cds {
my ($self) = @_;
$self->throw_not_implemented();
}
