Bio::Location::FuzzyLocationI(3)

NAME
Bio::Location::FuzzyLocationI - Abstract interface of a Location on a Sequence which has unclear start/end location

SYNOPSIS
    # Get a FuzzyLocationI object somehow
    print "Fuzzy FT location string is ", $location->to_FTstring();
    print "location is of the type ", $location->loc_type, "\n";

DESCRIPTION
This interface encapsulates the necessary methods for representing a Fuzzy Location, one that does not have clear start and/or end points. This will initially serve to handle features from Genbank/EMBL feature tables that are written as 1^100 meaning between bases 1 and 100 or <100..300 meaning it starts somewhere before 100. Advanced implementations of this interface may be able to handle the necessary logic of overlaps/intersection/contains/union. It was constructed to handle fuzzy locations that can be represented in Genbank/EMBL.

FEEDBACK
User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. 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 _

LocationI methods

  location_type
  Title   : loc_type
  Usage   : my $location_type = $location->location_type();
  Function: Get location type encoded as text
  Returns : string ('EXACT', 'WITHIN', 'IN-BETWEEN')
  Args    : none

Bio::LocationI methods
Bio::LocationI methods follow

  min_start
  Title   : min_start
  Usage   : my $minstart = $location->min_start();
  Function: Get minimum starting location of feature startpoint
  Returns : integer or undef if no maximum starting point.
  Args    : none

  max_start
  Title   : max_start
  Usage   : my $maxstart = $location->max_start();
  Function: Get maximum starting location of feature startpoint
  Returns : integer or undef if no maximum starting point.
  Args    : none

  start_pos_type
  Title   : start_pos_type
  Usage   : my $start_pos_type = $location->start_pos_type();
  Function: Get start position type (ie <,>, ^)
  Returns : type of position coded as text
            ('BEFORE', 'AFTER', 'EXACT','WITHIN', 'BETWEEN')
  Args    : none

  min_end
  Title   : min_end
  Usage   : my $minend = $location->min_end();
  Function: Get minimum ending location of feature endpoint
  Returns : integer or undef if no minimum ending point.
  Args    : none

  max_end
  Title   : max_end
  Usage   : my $maxend = $location->max_end();
  Function: Get maximum ending location of feature endpoint
  Returns : integer or undef if no maximum ending point.
  Args    : none

  end_pos_type
  Title   : end_pos_type
  Usage   : my $end_pos_type = $location->end_pos_type();
  Function: Get end position type (ie <,>, ^)
  Returns : type of position coded as text
            ('BEFORE', 'AFTER', 'EXACT','WITHIN', 'BETWEEN')
  Args    : none

  seq_id
  Title   : seq_id
  Usage   : my $seqid = $location->seq_id();
  Function: Get/Set seq_id that location refers to
  Returns : seq_id
  Args    : [optional] seq_id value to set

  coordinate_policy
  Title   : coordinate_policy
  Usage   : $policy = $location->coordinate_policy();
            $location->coordinate_policy($mypolicy); # set may not be possible
  Function: Get the coordinate computing policy employed by this object.

            See Bio::Location::CoordinatePolicyI for documentation about
            the policy object and its use.

            The interface *does not* require implementing classes to accept
            setting of a different policy. The implementation provided here
            does, however, allow one to do so.

            Implementors of this interface are expected to initialize every
            new instance with a CoordinatePolicyI object. The implementation
            provided here will return a default policy object if none has
            been set yet. To change this default policy object call this
            method as a class method with an appropriate argument. Note that
            in this case only subsequently created Location objects will be
            affected.

  Returns : A Bio::Location::CoordinatePolicyI implementing object.
  Args    : On set, a Bio::Location::CoordinatePolicyI implementing object.

  to_FTstring
  Title   : to_FTstring
  Usage   : my $locstr = $location->to_FTstring()
  Function: returns the FeatureTable string of this location
  Returns : string
  Args    : none
