Summary
Bio::Coordinate::Result - Results from coordinate transformation
Package variables
No package variables defined.
Inherit
Bio::Coordinate::ResultI Bio::Location::Split
Synopsis
  use Bio::Coordinate::Result;

  #get results from a Bio::Coordinate::MapperI
  $matched = $result->each_match;
Description
The results from Bio::Coordinate::MapperI are kept in an object which
itself is a split location, See Bio::Location::Split. The results
are either Matches or Gaps. See Bio::Coordinate::Result::Match and
Bio::Coordinate::Result::Gap.
If only one Match is returned, there is a convenience method of
retrieving it or accessing its methods. Same holds true for a Gap.

 Title   : add_result
 Usage   : $obj->add_result($result)
 Function: Adds the contents of one Bio::Coordinate::Result
 Example : 
 Returns : 1 when succeeds
 Args    : Result object

  Title   : seq_id
  Usage   : my $seqid = $location->seq_id();
  Function: Get/Set seq_id that location refers to

            We override this here in order to propagate to all sublocations
            which are not remote (provided this root is not remote either)

 Title   : match
 Usage   : $match_object = $obj->match(); #or

Mailing ListsTop
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 lists Your participation is much appreciated.

Support Top
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.
Reporting BugsTop
report bugs to the Bioperl bug tracking system to help us keep track
the bugs and their resolution. Bug reports can be submitted via the

APPENDIXTop
The rest of the documentation details each of the object
methods. Internal methods are usually preceded with a _
add_locationTop
 Title   : add_sub_Location
 Usage   : $obj->add_sub_Location($variant)
 Function: 

           Pushes one Bio::LocationI into the list of variants.

 Example : 
 Returns : 1 when succeeds
 Args    : Location object
Convenience methodsTop
These methods are shortcuts to Match and Gap locations.
