Bio::Map::PositionI - Abstracts the notion of a position having a value in the context of a marker and a Map


    # do not use directly


This object stores one of the postions a that a mappable object (e.g. Marker) may have in a map (e.g. restriction enzymes or a SNP mapped to several chromosomes).

The method numeric() returns the position in a form that can be compared between other positions of the same type.
