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.

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', '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 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
