NAME

Bio::Location::SplitLocationI - Abstract interface of a Location on a Sequence which has multiple locations (start/end points)

SYNOPSIS

  # 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++;
    }

DESCRIPTION

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.

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

sub_Location

Title   : sub_Location
Usage   : @locations = $feat->sub_Location();
Function: Returns an array of LocationI objects
Returns : An array
Args    : none

splittype

Title   : splittype
Usage   : $splittype = $fuzzy->splittype();
Function: get/set the split splittype
Returns : the splittype of split feature (join, order)
Args    : splittype to set

is_single_sequence

  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 methods

Bio::LocationI inherited 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
