Bio::Location::Simple(3)

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

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.

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   : $self->is_remote($newval)
 Function: Getset for is_remote value
 Returns : value of is_remote
 Args    : newvalue (optional)

  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
