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 : optionally 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 : optionally 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 : optionally 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
