NAME

Bio::Map::Position - A single position of a Marker in a Map

SYNOPSIS

    use Bio::Map::Position;
    my $position = new Bio::Map::Position(-map => $map, 
                                          -marker => $marker
                                          -value => 100
                                          );

DESCRIPTION

This object is an implementation of the PositionI interface that handles the specific values of a position. This allows an element (e.g. Marker) to have multiple positions within a map and still be treated as a single entity.

This does not directly handle the concept of a relative map in which no known exact positions exist but markers are just ordered relative to one another - in that case arbitrary values must be assigned for position values.

No units are assumed here - units are handled by context of which Map a position is placed in or the subclass of this Position.
