NAME ^

Bio::Map::Mappable - An object representing a generic map element that can have multiple locations in several maps.

SYNOPSIS ^

  # a map element in two different positions on the same map
  $map1 = Bio::Map::SimpleMap->new();
  $position1 = Bio::Map::Position->new(-map => $map1, -value => 100);
  $position2 = Bio::Map::Position->new(-map => $map1, -value => 200);
  $mappable = Bio::Map::Mappable->new(-positions => [$position1, $position2] );

  # add another position on a different map
  $map2 = Bio::Map::SimpleMap->new();
  $position3 = Bio::Map::Position->new(-map => $map2, $value => 50);
  $mappable->add_position($position3);

  # get all the places our map element is found, on a particular map of interest
  foreach $pos ($mappable->get_positions($map1)) {
     print $pos->value, "\n";
  }

DESCRIPTION ^

This object handles the notion of a generic map element. Mappables are entities with one or more positions on one or more maps.

This object is a pure perl implementation of Bio::Map::MappableI. That interface implements some of its own methods so check the docs there for those.

FEEDBACK ^

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.
