NAME

       Bio::SeqFeature::Gene::ExonI - Interface for a feature representing an exon

SYNOPSIS

       See documentation of methods.

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.

FEEDBACK

   Mailing Lists
       User feedback is an integral part of the evolution of this and other Bioperl modules. Send
       your comments and suggestions preferably
        to one of the Bioperl mailing lists.  Your participation is much appreciated.

   Support
       Please direct usage questions or support issues to the mailing list:

       bioperl-l@bioperl.org

       rather than to the module maintainer directly. Many experienced and reponsive experts will
       be able look at the problem and quickly address it. Please include a thorough description
       of the problem with code and data examples if at all possible.

   Reporting Bugs
       Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their
       resolution.  Bug reports can be submitted via the web:

APPENDIX

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

   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    :

   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    :
