Bio::Map::OrderedPosition(3) Abstracts the notion of a member


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 in.

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
