Bio::Location::FuzzyLocationI - Abstract interface of a Location on a Sequence which has unclear start/end location
# Get a FuzzyLocationI object somehow print "Fuzzy FT location string is ", $location->to_FTstring(); print "location is of the type ", $location->loc_type, "\n";
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.

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.

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
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 follow
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
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
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
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
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
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
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
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.
Title : to_FTstring Usage : my $locstr = $location->to_FTstring() Function: returns the FeatureTable string of this location Returns : string Args : none
