NAME

Bio::Location::Simple - Implementation of a Simple Location on a Sequence

CONTENTS

SYNOPSIS



    use Bio::Location::Simple;

    my $location = Bio::Location::Simple->new(
        -start  => 1,
        -end    => 100,
        -strand => 1,
    );

    if( $location->strand == -1 ) {
        printf "complement(%d..%d)\n", $location->start, $location->end;
    } else {
        printf "%d..%d\n", $location->start, $location->end;
    }



DESCRIPTION

This is an implementation of Bio::LocationI to manage exact location information on a Sequence: ’22’ or ’12..15’ or ’16^17’.

You can test the type of the location using length() function () or directly location_type() which can one of two values: ’EXACT’ or ’IN-BETWEEN’.

FEEDBACK

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.

    Support

Please direct usage questions or support issues to the mailing list:

bioperl-l@bioperl.org

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.

    Reporting Bugs

Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their resolution. Bug reports can be submitted via the web:

APPENDIX

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

    start



  Title   : start
  Usage   : $start = $loc->start();
  Function: get/set the start of this range
  Returns : the start of this range
  Args    : optionaly allows the start to be set
            using $loc->start($start)



    end



  Title   : end
  Usage   : $end = $loc->end();
  Function: get/set the end of this range
  Returns : the end of this range
  Args    : optionaly allows the end to be set
          : using $loc->end($start)
  Note    : If start is set but end is undefined, this now assumes that start
            is the same as end but throws a warning (i.e. it assumes this is
            a possible error). If start is undefined, this now throws an
            exception.



    strand



  Title   : strand
  Usage   : $strand = $loc->strand();
  Function: get/set the strand of this range
  Returns : the strandedness (-1, 0, +1)
  Args    : optionaly allows the strand to be set
          : using $loc->strand($strand)



    length



 Title   : length
 Usage   : $len = $loc->length();
 Function: get the length in the coordinate space this location spans
 Example :
 Returns : an integer
 Args    : none



    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 minimum starting point.
  Args    : none



    max_start



  Title   : max_start
  Usage   : my $maxstart = $location->max_start();
  Function: Get maximum starting location of feature startpoint.

            In this implementation this is exactly the same as min_start().

  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

            In this implementation this is exactly the same as min_end().

  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



    location_type



  Title   : location_type
  Usage   : my $location_type = $location->location_type();
  Function: Get location type encoded as text
  Returns : string (EXACT or IN-BETWEEN)
  Args    : EXACT or .. or IN-BETWEEN or ^



    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



    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
