=head1 NAME

Bio::Map::CytoMap - A Bio::MapI compliant map implementation handling cytogenic bands 

=head1 SYNOPSIS

    use Bio::Map::CytoMap;
    my $map = new Bio::Map::CytoMap(-name => 'human1',
				      -species => $human);
    foreach my $marker ( @markers ) { # get a list of markers somewhere
	$map->add_element($marker);
    }

=head1 DESCRIPTION

This is the simple implementation of cytogenetic maps based on
L<Bio::Map::MapI>.  It handles the essential storage of name, species,
type, and units as well as in memory representation of the elements of
a map.

For CytoMaps type is hard coded to be 'cytogeneticmap' and
units are set to '' but can be set to something else.

=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::Map::CytoMap;
use vars qw(@ISA $MAPCOUNT);
use strict;

# Object preamble - inherits from Bio::Root::Root

use Bio::Root::Root;
use Bio::Map::SimpleMap;

@ISA = qw(Bio::Root::Root Bio::Map::SimpleMap);
BEGIN { $MAPCOUNT = 1; }

=head2 Modified methods 

All methods present in L<Bio::Map::SimpleMap> are implemted by this
class. Most of the methods are inherited from SimpleMap. The following
methods have been modified to refelect the needs of cytogenetic maps.

=head2 new

 Title   : new
 Usage   : my $obj = new Bio::Map::CytoMap();
 Function: Builds a new Bio::Map::CytoMap object
 Returns : Bio::Map::CytoMap
 Args    : -name    => name of map (string)
           -species => species for this map (Bio::Species) [optional]
           -elements=> elements to initialize with
                       (arrayref of Bio::Map::MappableI objects) [optional]

           -uid     => Unique Id
=cut

sub new {
    my($class,@args) = @_;

    my $self = $class->SUPER::new(@args);

    $self->{'_elements'} = [];
    $self->{'_name'}     = '';
    $self->{'_species'}  = '';
    $self->{'_units'}    = '';
    $self->{'_type'}    = 'cyto';
    $self->{'_uid'} = $MAPCOUNT++;
    my ($name, $type,$species, $units,
	$elements,$uid) = $self->_rearrange([qw(NAME TYPE
						SPECIES UNITS
						ELEMENTS UID)], @args);
    defined $name     && $self->name($name);
    defined $species  && $self->species($species);
    defined $units    && $self->units($units);
    defined $type     && $self->type($type);
    defined $uid      && $self->unique_id($uid);

    if( $elements && ref($elements) =~ /array/ ) {
	foreach my $item ( @$elements ) {
	    $self->add_element($item);
	}
    }
    return $self;
}

=head2 type

 Title   : type
 Usage   : my $type = $map->type
 Function: Get hard-coded  Map type
 Returns : String coding map type
 Args    : 

=cut

sub type {
   my ($self) = @_;
   return $self->{'_type'};
}


=head2 length

 Title   : length
 Usage   : my $length = $map->length();
 Function: Retrieves the length of the map,
 Returns : undef since length is not calculatable for 
           cytogenetic maps
 Args    : none

=cut

sub length{
   my ($self,@args) = @_;
   return undef;
}
