Bio::LiveSeq::Exon - Range abstract class for LiveSeq


  # documentation needed


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).

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


  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


  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
