=head1 NAME
Bio::Map::PositionWithSequence - A position with a sequence.
=head1 SYNOPSIS
use Bio::Map::PositionWithSequence;
my $pos = Bio::Map::PositionWithSequence->new(-map => $map,
-element => $element,
-start => 0,
-seq => 'ATGC');
=head1 DESCRIPTION
Have a position with a sequence, eg. define what the binding site sequence of
a certain transcription factor binding site is by modelling it as one of these
objects with the -element assigned to a Bio::Map::TranscriptionFactor instance.
=head1 FEEDBACK
=head2 Mailing Lists
User feedback is an integral part of the evolution of this and other
Bioperl modules. Send your comments and suggestions preferably to
the Bioperl mailing list. Your participation is much appreciated.

=head2 Support
Please direct usage questions or support issues to the mailing list:
I<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.

=head1 APPENDIX
The rest of the documentation details each of the object methods.
Internal methods are usually preceded with a _
=cut
# Let the code begin...
package Bio::Map::PositionWithSequence;
use strict;
use base qw(Bio::Map::Position Bio::LocatableSeq);
=head2 new
Title : new
Usage : my $obj = Bio::Map::PositionWithSequence->new();
Function: Builds a new Bio::Map::PositionWithSequence object
Returns : Bio::Map::PositionWithSequence
Args : -map => Bio::Map::GeneMap object
-element => Bio::Map::Gene object
-relative => Bio::Map::GeneRelative object
-seq => string, length of this string will set the length
of this position's range
* If this position has no range, or if a single value can describe
the range *
-value => scalar : something that describes the single
point position or range of this
Position, most likely an int
* Or if this position has a range, at least two of *
-start => int : value of the start co-ordinate
-end => int : value of the end co-ordinate
-length => int : length of the range

sub new {
my ($class, @args) = @_;
my $self = $class->SUPER::new(@args);
my ($seq) = $self->_rearrange([qw( SEQ )], @args);
$self->seq($seq) if $seq;
return $self;
}
=head2 seq
Title : seq
Usage : my $string = $obj->seq();
Function: Get/set the sequence as a string of letters.
Returns : scalar
Args : Optionally on set the new value (a string). An optional second
argument presets the alphabet (otherwise it will be guessed).
=cut

my ($self, $str, $alpha) = @_;
# done like this because SUPER will set seq to undef if undef supplied,
# but GeneMap wants to send undef, undef, 1 to decendants of this method
