NAME

Bio::Map::RelativeI - Interface for describing what a Position's coordiantes are relative to.

SYNOPSIS

# do not use this module directly
# See Bio::Map::Relative for an example of
# implementation.

DESCRIPTION

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.

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.

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.

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

absolute_conversion

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

type

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

map

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.

element

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

position

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

description

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
