Bio::Map::RelativeI - Interface for describing what a Position's coordiantes are relative to.
# do not use this module directly # See Bio::Map::Relative for an example of # implementation.
A Relative object is used to describe what the co-ordinates (numerical(), start(), end()) of a Position are relative to. By default they are implicitly assumed to be relative to the start of the map the Position is on. But setting the relative() of a Position to one of these objects lets us define otherwise.
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.

Please direct usage questions or support issues to the mailing list:
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.
Report bugs to the Bioperl bug tracking system to help us keep track of the bugs and their resolution. Bug reports can be submitted via the web:
The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
Title : absolute_conversion Usage : my $absolute_coord = $relative->absolute_conversion($pos); Function: Convert the start co-ordinate of the supplied position into a number relative to the start of its map. Returns : scalar number Args : Bio::Map::PositionI object
Title : type Usage : my $type = $relative->type(); Function: Get the type of thing we are relative to. The types correspond to a method name, so the value of what we are relative to can subsequently be found by $value = $relative->$type; Note that type is set by the last method that was set, or during new(). Returns : the string 'map', 'element' or 'position', or undef Args : none
Title : map Usage : my $int = $relative->map(); $relative->map($int); Function: Get/set the distance from the start of the map that the Position's co-ordiantes are relative to. Returns : int Args : none to get, OR int to set; a value of 0 means relative to the start of the map.
Title : element Usage : my $element = $relative->element(); $relative->element($element); Function: Get/set the map element (Mappable) the Position is relative to. If the Mappable has more than one Position on the Position's map, we will be relative to the Mappable's first Position on the map. Returns : Bio::Map::MappableI Args : none got get, OR Bio::Map::MappableI to set
Title : position Usage : my $position = $relative->position(); $relative->position($position); Function: Get/set the Position your Position is relative to. Your Position will be made relative to the start of this supplied Position. It makes no difference what maps the Positions are on. Returns : Bio::Map::PositionI Args : none got get, OR Bio::Map::PositionI to set
Title : description Usage : my $description = $relative->description(); $relative->description($description); Function: Get/set a textual description of what this relative describes. Returns : string Args : none to get, OR string to set
