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 $ph = new Bio::Map::PositionHandler($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.
