Bio::Location::SplitLocationI - Abstract interface of a Location on a Sequence which has multiple locations (start/end points)
# get a SplitLocationI somehow
print $splitlocation->start, "..", $splitlocation->end, "\n";
my @sublocs = $splitlocation->sub_Location();
my $count = 1;
# print the start/end points of the sub locations
foreach my $location ( sort { $a->start <=> $b->start } @sublocs ) {
printf "sub feature %d [%d..%d]\n", $location->start,$location->end;
$count++;
}
This interface encapsulates the necessary methods for representing the location of a sequence feature that has more that just a single start/end pair. Some examples of this are the annotated exons in a gene or the annotated CDS in a sequence file.
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.

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
Title : sub_Location Usage : @locations = $feat->sub_Location(); Function: Returns an array of LocationI objects Returns : An array Args : none
Title : splittype Usage : $splittype = $fuzzy->splittype(); Function: get/set the split splittype Returns : the splittype of split feature (join, order) Args : splittype to set
Title : is_single_sequence
Usage : if($splitloc->is_single_sequence()) {
print "Location object $splitloc is split ".
"but only across a single sequence\n";
}
Function: Determine whether this location is split across a single or
multiple sequences.
Returns : TRUE if all sublocations lie on the same sequence as the root
location (feature), and FALSE otherwise.
Args : none
Bio::LocationI inherited 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
