       Bio::Map::OrderedPosition - Abstracts the notion of a member      of an ordered list of
       markers. Each marker is a certain distance      from the one in the ordered list before


           use Bio::Map::OrderedPosition;
               # the first marker in the sequence
           my $position = Bio::Map::OrderedPosition->new(-order => 1,
                               -positions => [ [ $map, 22.3] ] );
               # the second marker in the sequence, 15.6 units from the fist one
           my $position2 = Bio::Map::OrderedPosition->new(-order => 2,
                               -positions => [ [ $map, 37.9] ] );
               # the third marker in the sequence, coincidental with the second
               # marker
           my $position3 = Bio::Map::OrderedPosition->new(-order => 3,
                               -posititions => [ [ $map, 37.9]] );


       This object is an implementation of the PositionI interface and the Position object
       handles the specific values of a position.  OrderedPosition is intended to be slightly
       more specific then Position but only specific enough for a parser from the MarkerIO
       subsystem to create and then pass to a client application to bless into the proper type.
       For an example of how this is intended to work, see the

       No units are assumed here - units are handled by context of which Map a position is placed

       Se Bio::Map::Position for additional information.


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

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

       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 of the bugs and their

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

        Title   : new
        Usage   : my $obj = Bio::Map::OrderedPosition->new();
        Function: Builds a new Bio::Map::OrderedPosition object
        Returns : Bio::Map::OrderedPosition
        Args    : -order : The order of this position

        Title   : order
        Usage   : $o_position->order($new_order);
                  my $order = $o_position->order();
        Function: Get/set the order position of this position in a map.
        Returns : int, the order of this position
        Args    : none to get, OR int to set

        Title   : sortable
        Usage   : my $num = $position->sortable();
        Function: Read-only method that is guaranteed to return a value suitable
                  for correctly sorting this kind of position amongst other positions
                  of the same kind on the same map. Note that sorting different kinds
                  of position together is unlikely to give sane results.
        Returns : numeric
        Args    : none

        Title   : equals
        Usage   : if ($mappable->equals($mapable2)) {...}
        Function: Test if a position is equal to another position.
        Returns : boolean
        Args    : Bio::Map::PositionI

        Title   : less_than
        Usage   : if ($mappable->less_than($m2)) {...}
        Function: Tests if a position is less than another position
                  It is assumed that 2 positions are in the same map.
        Returns : boolean
        Args    : Bio::Map::PositionI

        Title   : greater_than
        Usage   : if ($mappable->greater_than($m2)) {...}
        Function: Tests if position is greater than another position.
                  It is assumed that 2 positions are in the same map.
        Returns : boolean
        Args    : Bio::Map::PositionI
