12 =head1 NAME
14 Bio::Location::FuzzyLocationI - Abstract interface of a Location on a Sequence
15 which has unclear start/end location
17 =head1 SYNOPSIS
19 # Get a FuzzyLocationI object somehow
20 print "Fuzzy FT location string is ", $location->to_FTstring();
21 print "location is of the type ", $location->loc_type, "\n";
23 =head1 DESCRIPTION
25 This interface encapsulates the necessary methods for representing a
26 Fuzzy Location, one that does not have clear start and/or end points.
27 This will initially serve to handle features from Genbank/EMBL feature
28 tables that are written as 1^100 meaning between bases 1 and 100 or
29 E<lt>100..300 meaning it starts somewhere before 100. Advanced
30 implementations of this interface may be able to handle the necessary
31 logic of overlaps/intersection/contains/union. It was constructed to
32 handle fuzzy locations that can be represented in Genbank/EMBL.
34 =head1 FEEDBACK
36 User feedback is an integral part of the evolution of this and other
37 Bioperl modules. Send your comments and suggestions preferably to one
38 of the Bioperl mailing lists. Your participation is much appreciated.

43 =head2 Support
45 Please direct usage questions or support issues to the mailing list:
47 I<bioperl-l@bioperl.org>
49 rather than to the module maintainer directly. Many experienced and
50 reponsive experts will be able look at the problem and quickly
51 address it. Please include a thorough description of the problem
52 with code and data examples if at all possible.
54 =head2 Reporting Bugs
56 Report bugs to the Bioperl bug tracking system to help us keep track
57 the bugs and their resolution. Bug reports can be submitted via the web:

101 =head2 min_start
103 Title : min_start
104 Usage : my $minstart = $location->min_start();
105 Function: Get minimum starting location of feature startpoint
106 Returns : integer or undef if no maximum starting point.
107 Args : none
109 =cut
111 =head2 max_start
113 Title : max_start
114 Usage : my $maxstart = $location->max_start();
115 Function: Get maximum starting location of feature startpoint
116 Returns : integer or undef if no maximum starting point.
117 Args : none
119 =cut
121 =head2 start_pos_type
123 Title : start_pos_type
124 Usage : my $start_pos_type = $location->start_pos_type();
125 Function: Get start position type (ie <,>, ^)
126 Returns : type of position coded as text
127 ('BEFORE', 'AFTER', 'EXACT','WITHIN', 'BETWEEN')
128 Args : none
130 =cut
132 =head2 min_end
134 Title : min_end
135 Usage : my $minend = $location->min_end();
136 Function: Get minimum ending location of feature endpoint
137 Returns : integer or undef if no minimum ending point.
138 Args : none
140 =cut
142 =head2 max_end
144 Title : max_end
145 Usage : my $maxend = $location->max_end();
146 Function: Get maximum ending location of feature endpoint
147 Returns : integer or undef if no maximum ending point.
148 Args : none
150 =cut
152 =head2 end_pos_type
154 Title : end_pos_type
155 Usage : my $end_pos_type = $location->end_pos_type();
156 Function: Get end position type (ie <,>, ^)
157 Returns : type of position coded as text
158 ('BEFORE', 'AFTER', 'EXACT','WITHIN', 'BETWEEN')
159 Args : none
161 =cut
163 =head2 seq_id
165 Title : seq_id
166 Usage : my $seqid = $location->seq_id();
167 Function: Get/Set seq_id that location refers to
168 Returns : seq_id
169 Args : [optional] seq_id value to set
171 =cut
173 =head2 coordinate_policy
175 Title : coordinate_policy
176 Usage : $policy = $location->coordinate_policy();
177 $location->coordinate_policy($mypolicy); # set may not be possible
178 Function: Get the coordinate computing policy employed by this object.
180 See Bio::Location::CoordinatePolicyI for documentation about
181 the policy object and its use.
183 The interface *does not* require implementing classes to accept
184 setting of a different policy. The implementation provided here
185 does, however, allow to do so.
187 Implementors of this interface are expected to initialize every
188 new instance with a CoordinatePolicyI object. The implementation
189 provided here will return a default policy object if none has
190 been set yet. To change this default policy object call this
191 method as a class method with an appropriate argument. Note that
192 in this case only subsequently created Location objects will be
193 affected.
195 Returns : A Bio::Location::CoordinatePolicyI implementing object.
196 Args : On set, a Bio::Location::CoordinatePolicyI implementing object.
198 =cut
200 =head2 to_FTstring
202 Title : to_FTstring
203 Usage : my $locstr = $location->to_FTstring()
204 Function: returns the FeatureTable string of this location
205 Returns : string
206 Args : none
