  Returns : string ('EXACT', 'WITHIN', 'IN-BETWEEN')
  Args    : none

is_remote

 Title   : is_remote
 Usage   : $is_remote_loc = $loc->is_remote()
 Function: Whether or not a location is a remote location.
           A location is said to be remote if it is on a different
           'object' than the object which 'has' this
           location. Typically, features on a sequence will sometimes
           have a remote location, which means that the location of
           the feature is on a different sequence than the one that is
           attached to the feature. In such a case, $loc->seq_id will
           be different from $feat->seq_id (usually they will be the
           same).
           While this may sound weird, it reflects the location of the
           kind of AL445212.9:83662..166657 which can be found in GenBank/EMBL
           feature tables.
 Example : 
 Returns : TRUE if the location is a remote location, and FALSE otherwise
 Args    : Value to set to

each_Location

 Title   : each_Location
 Usage   : @locations = $locObject->each_Location($order);
 Function: Conserved function call across Location:: modules - will
           return an array containing the component Location(s) in
           that object, regardless if the calling object is itself a
           single location or one containing sublocations.
 Returns : an array of Bio::LocationI implementing objects - for
           Simple locations, the return value is just itself.
 Args    :

to_FTstring

  Title   : to_FTstring
  Usage   : my $locstr = $location->to_FTstring()
  Function: returns the FeatureTable string of this location
  Returns : string
  Args    : none

valid_Location

 Title   : valid_Location
 Usage   : if ($location->valid_location) {...};
 Function: boolean method to determine whether location is considered valid
           (has minimum requirements for Simple implementation)
 Returns : Boolean value: true if location is valid, false otherwise
 Args    : none

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 L<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
            L<Bio::Location::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 L<Bio::Location::CoordinatePolicyI> implementing object.
  Args    : On set, a L<Bio::Location::CoordinatePolicyI> implementing object.

trunc

  Title   : trunc
        Usage   : $trunc_location = $location->trunc($start, $end, $relative_ori);
        Function: To truncate a location and keep annotations and features
                  within the truncated segment intact.
                                                This might do things differently where the truncation
                                                splits the location in half.
        CAVEAT  : As yet, this is an untested and unannounced method. Use
                  with caution!
        Returns : A L<Bio::Location::Atomic> object.
        Args    : The start and end position for the trunction, and the relative
                  orientation.
