=head1 NAME

Bio::Seq::RichSeqI - RichSeq interface, mainly for database orientated sequences

=head1 SYNOPSIS

    @secondary   = $richseq->get_secondary_accessions;
    $division    = $richseq->division;
    $mol         = $richseq->molecule;
    @dates       = $richseq->get_dates; 
    $seq_version = $richseq->seq_version;  
    $pid         = $richseq->pid;
    $keywords    = $richseq->keywords;

=head1 DESCRIPTION

This interface extends the Bio::SeqI interface to give additional functionality
to sequences with richer data sources, in particular from database sequences 
(EMBL, GenBank and Swissprot).

# Let the code begin...


package Bio::Seq::RichSeqI;
use vars qw(@ISA);
use strict;
use Bio::SeqI;

@ISA = ('Bio::SeqI');


=head2 get_secondary_accessions

 Title   : get_secondary_accessions
 Usage   : 
 Function: Get the secondary accessions for a sequence.
 Example :
 Returns : an array of strings
 Args    : none


=cut

sub get_secondary_accessions{
   my ($self,@args) = @_;

   $self->throw("hit get_secondary_accessions in interface definition - error");

}


=head2 division

 Title   : division
 Usage   :
 Function: Get (and set, depending on the implementation) the divison for
           a sequence.

           Examples from GenBank are PLN (plants), PRI (primates), etc.
 Example :
 Returns : a string
 Args    :


=cut

sub division{
   my ($self,@args) = @_;

   $self->throw("hit division in interface definition - error");

}


=head2 molecule

 Title   : molecule
 Usage   :
 Function: Get (and set, depending on the implementation) the molecule
           type for the sequence.

           This is not necessarily the same as Bio::PrimarySeqI::alphabet(),
           because it is databank-specific.
 Example :
 Returns : a string
 Args    :


=cut

sub molecule{
   my ($self,@args) = @_;

   $self->throw("hit molecule in interface definition - error");
}

=head2 pid

 Title   : pid
 Usage   :
 Function: Get (and set, depending on the implementation) the PID property
           for the sequence.
 Example :
 Returns : a string
 Args    :


=cut

sub pid {
   my ($self,@args) = @_;

   $self->throw("hit pid in interface definition - error");
}

=head2 get_dates

 Title   : get_dates
 Usage   :
 Function: Get (and set, depending on the implementation) the dates the
           databank entry specified for the sequence
 Example :
 Returns : an array of strings
 Args    :


=cut

sub get_dates{
   my ($self,@args) = @_;

   $self->throw("hit get_dates in interface definition - error");

}


=head2 seq_version

 Title   : seq_version
 Usage   :
 Function: Get (and set, depending on the implementation) the version string
           of the sequence.
 Example :
 Returns : a string
 Args    :


=cut

sub seq_version{
   my ($self,@args) = @_;

   $self->throw("hit seq_version in interface definition - error");

}

=head2 keywords

 Title   : keywords
 Usage   : $obj->keywords($newval)
 Function: 
 Returns : value of keywords (a string)
 Args    : newvalue (optional) (a string)


=cut

sub keywords {
   my ($self) = @_;
   $self->throw("hit keywords in interface definition - error");
}
