Raw content of Bio::DB::GFF::Homol =head1 NAME Bio::DB::GFF::Homol -- A segment of DNA that is homologous to another =head1 SYNOPSIS See L<Bio::DB::GFF>. =head1 DESCRIPTION Bio::DB::GFF::Homol is a named subtype of Bio::DB::GFF::Segment. It inherits all the methods of its parent, and was created primarily to allow for isa() queries and for compatibility with Ace::Sequence::Homol. A Homol object is typically returned as the method result of the Bio::DB::GFF::Feature-E<gt>target() method. =head1 METHODS =cut package Bio::DB::GFF::Homol; use strict; use Bio::DB::GFF::Segment; use vars qw(@ISA); @ISA = 'Bio::DB::GFF::Segment'; =head2 name Title : name Usage : $name = $homol->name Function: get the ID of the homology object Returns : a string Args : none Status : Public =cut sub name { shift->refseq } =head2 asString Title : asString Usage : $name = $homol->asString Function: same as name(), for operator overloading Returns : a string Args : none Status : Public =cut sub asString { shift->name } =head2 id Title : id Usage : $id = $homol->id Function: get database ID in class:id format Returns : a string Args : none Status : Public =cut sub id { my $self = shift; return "$self->{class}:$self->{name}"; } sub new_from_segment { my $package = shift; $package = ref $package if ref $package; my $segment = shift; my $new = {}; @{$new}{qw(factory sourceseq start stop strand class ref refstart refstrand)} = @{$segment}{qw(factory sourceseq start stop strand class ref refstart refstrand)}; return bless $new,__PACKAGE__; } =head1 BUGS This module is still under development. =head1 SEE ALSO L<bioperl>, L<Bio::DB::GFF>, L<Bio::DB::RelSegment> =head1 AUTHOR Lincoln Stein E<lt>lstein@cshl.orgE<gt>.
