module Bio::Map::ActsLikeMap

Description ↑

The Bio::Map::ActsLikeMap module contains methods that are typical for map-like things:

Classes that include this mixin should provide an array property called mappings_as_map.

For example:

class MyMapThing
  include Bio::Map::ActsLikeMap

  def initialize(name)
    @name = name
    @mappings_as_maps = Array.new
  end
  attr_accessor :name, :mappings_as_map
 end

Public Instance Methods

add_mapping_as_map(marker, location = nil) click to toggle source

Description ↑

Adds a Bio::Map::Mappings object to its array of mappings.

Usage ↑

# suppose we have a Bio::Map::SimpleMap object called my_map
my_map.add_mapping_as_map(Bio::Map::Marker.new('marker_a'), '5')

Arguments:

  • marker (required): Bio::Map::Marker object

  • location: location of mapping. Should be a string, not a number.

Returns

itself

118     raise "[Error] marker is not object that implements Bio::Map::ActsLikeMarker"
119   end
120   my_mapping = ( location.nil? ) ? Bio::Map::Mapping.new(self, marker, nil) : Bio::Map::Mapping.new(self, marker, Bio::Locations.new(location))

122     self.mappings_as_map.push(my_mapping)
