/ Bio::Map::OrderedPositionWithDistance

NAME

Bio::Map::OrderedPositionWithDistance - 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 it.

SYNOPSIS

    use Bio::Map::OrderedPositionWithDistance;
	# the first marker in the sequence
    my $position = new Bio::Map::OrderedPositionWithDistance(-positions => 1,
			-distance => 22.3 );
	# the second marker in the sequence, 15.6 units from the fist one
    my $position2 = new Bio::Map::OrderedPositionWithDistance(-positions => 2,
			-distance => 15.6 );
	# the third marker in the sequence, coincidental with the second
	# marker
    my $position3 = new Bio::Map::OrderedPositionWithDistance(-positions => 3,
			-distance => 0 );

DESCRIPTION

This object is an implementation of the PositionI interface and the Position object handles the specific values of a position. OrderedPositionWithDistance 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 Mapmaker.pm.

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

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

APPENDIX

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

new

 Title   : new
 Usage   : my $obj = new Bio::Map::OrderedPositionWithDistance();
 Function: Builds a new Bio::Map::OrderedPositionWithDistance object 
 Returns : Bio::Map::OrderedPositionWithDistance
 Args    : -positions  - Should be a single value representing the order
	of this marker within the list of markers
	-distance - The distance this marker is from the marker before it.
		0 reflects coincidentality.

distance($new_distance)

Title   : distance($new_distance)
Usage   : $position->distance(new_distance) _or_
       $position->distance()
Function: get/set the distance of this position from the previous marker
Returns : A scalar representing the current distance for this position.
Args    : If $new_distance is provided the distance of this Position will
       be set to $new_distance
