DESCRIPTION
This class represents a one continuous match between two coordinate systems represented by Bio::Location::Simple objects. The relationship is directed and reversible. It implements methods to ensure internal consistency, and map continuous and split locations from one coordinate system to another.This class is an elaboration of Bio::Coordinate::Pair. The map function returns only matches which is the mode needed most of tehtime. By default the matching regions between coordinate systems are boundless, so that you can say e.g. that gene starts from here in the chromosomal coordinate system and extends indefinetely in both directions. If you want to define the matching regions exactly, you can do that and set strict() to true.
new
strict
Title : strict Usage : $obj->strict(1); Function: Set and read the strictness of the coordinate system. Example : Returns : value of input system Args : boolean
map
Title : map Usage : $newpos = $obj->map($loc); Function: Map the location from the input coordinate system to a new value in the output coordinate system. In extrapolating coodinate system there is no location zero. Locations are... Example : Returns : new location in the output coordinate system or undef Args : Bio::Location::Simple
_map
Title : _map Usage : $newpos = $obj->_map($simpleloc); Function: Internal method that does the actual mapping. Called multiple times by map() if the location to be mapped is a split location Example : Returns : new location in the output coordinate system or undef Args : Bio::Location::Simple
