NAME

Bio::Map::PositionHandler - A Position Handler Implementation

SYNOPSIS

     # This is used by modules when they want to implement being a
     # Position or being something that has Positions (when they are
     # a L<Bio::Map::EntityI>)
 
     # Make a PositionHandler that knows about you
     my $ph = Bio::Map::PositionHandler->new($self);
 
     # Register with it so that it handles your Position-related needs
     $ph->register;
 
     # If you are a position, get/set the map you are on and the marker you are
     # for
     $ph->map($map);
     $ph->element($marker);
     my $map = $ph->map;
     my $marker = $ph->element;
 
     # If you are a marker, add a new position to yourself
     $ph->add_positions($pos);
 
     # And then get all your positions on a particular map
     foreach my $pos ($ph->get_positions($map)) {
         # do something with this Bio::Map::PositionI
     }
 
     # Or find out what maps you exist on
     my @maps = $ph->get_other_entities;
 
     # The same applies if you were a map
 
 

DESCRIPTION

A Position Handler copes with the coordination of different Bio::Map::EntityI objects, adding and removing them from each other and knowning who belongs to who. These relationships between objects are based around shared Positions, hence PositionHandler.

This PositionHandler is able to cope with Bio::Map::PositionI objects, Bio::Map::MappableI objects and Bio::Map::MapI objects.

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.

Support

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

bioperl-l@bioperl.org

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.
