=head1 NAME
Bio::LiveSeq::Exon - Range abstract class for LiveSeq
=head1 SYNOPSIS
# documentation needed
=head1 DESCRIPTION
Class for EXON objects. They consist of a beginlabel, an endlabel (both
referring to a LiveSeq DNA object) and a strand.
The strand could be 1 (forward strand, default), -1 (reverse strand).

=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::LiveSeq::Exon;
use strict;
use base qw(Bio::LiveSeq::Range);
=head2 new
Title : new
Usage : $exon1 = Bio::LiveSeq::Exon-> new(-seq => $objref,
-start => $startlabel,
-end => $endlabel, -strand => 1);
Function: generates a new Bio::LiveSeq::Exon
Returns : reference to a new object of class Exon
Errorcode -1
Args : two labels and an integer
=cut
=head2 get_Transcript
Title : get_Transcript
Usage : $transcript = $obj->get_Transcript()
Function: retrieves the reference to the object of class Transcript (if any)
attached to a LiveSeq object
Returns : object reference
Args : none
Note : only Exons that compose a Transcript (i.e. those created out of
a CDS Entry-Feature) will have an attached Transcript
=cut
sub get_Transcript {
my $self=shift;
return ($self->{'transcript'}); # this is set on all Exons a Transcript is made of when Transcript->new is called
}
# this checks if the attached Transcript has a Gene object attached

my ($self,$value) = @_;

$self->{'gene'} = $value;
