=head1 NAME

Bio::ClusterI - Cluster Interface 

=head1 SYNOPSIS

# see the implementations of this interface for details but
# basically

    my $cluster= $cluster->new(-description=>"POLYUBIQUITIN",
                               -members    =>[$seq1,$seq2]);
    my @members = $cluster->get_members();
    my @sub_members = $cluster->get_members(-species=>"homo sapiens");



=head1 DESCRIPTION

This interface is the basic structure for a cluster of bioperl objects.
In this case it is up to the implementer to check arguments
and initialize whatever new object the implementing class is designed for.

=head1 APPENDIX

The rest of the documentation details each of the object methods.
Internal methods are usually preceded with a _

package Bio::ClusterI;
use vars qw(@ISA);
use strict;

use Bio::Root::RootI;

@ISA = qw(Bio::Root::RootI);

=head1 Implementation Specific Functions

These functions are the ones that a specific implementation must
define.

=head2 new

  We dont mandate but encourage implementors to support at least the
  following named parameters upon object initialization.

  Argument        Description
  --------        -----------
  -display_id     the display ID or name for the cluster
  -description    the consensus description or name of the cluster
  -members        the array of objects belonging to the family

=cut

=head2 display_id

 Title   : display_id
 Usage   : 
 Function: Get the display name or identifier for the cluster
 Returns : a string
 Args    : 

=cut

sub display_id{
    shift->throw_not_implemented();
}


=head2 description

 Title   : description
 Usage   : Bio::ClusterI->description("POLYUBIQUITIN")
 Function: get/set for the consensus description of the cluster
 Returns : the description string 
 Args    : Optional the description string 

=cut

sub description{
    shift->throw_not_implemented();
}

=head2 size

 Title   : size
 Usage   : Bio::ClusterI->size();
 Function: get/set for the size of the family, 
           calculated from the number of members
 Returns : the size of the family 
 Args    : 

=cut

sub size {
    shift->throw_not_implemented();
}

=head2 cluster_score

 Title   : cluster_score
 Usage   : $cluster ->cluster_score(100);
 Function: get/set for cluster_score which
           represent the score in which the clustering
           algorithm assigns to this cluster.
 Returns : a number

=cut

sub cluster_score{
    shift->throw_not_implemented();
}

=head2 get_members

 Title   : get_members
 Usage   : Bio::ClusterI->get_members(($seq1, $seq2));
 Function: retrieve the members of the family by some criteria, for
           example :
           $cluster->get_members(-species => 'homo sapiens'); 

           Will return all members if no criteria are provided.

 Returns : the array of members
 Args    : 

=cut

sub get_members {
    shift->throw_not_implemented();
}

1;
