=head2 new()
Title : new()
Usage : $residue = Bio::Structure::Residue->new(
-id => 'human_id',
);
Function: Returns a new Bio::Structure::Residue object from basic
constructors. Probably most called from Bio::Structure::IO.
Returns : a new Bio::Structure::Residue object

sub new {
my ($class, @args) = @_;
my $self = $class->SUPER::new(@args);
my($id, $atom ) =
$self->_rearrange([qw(
ID
ATOM
)],
@args);
$id && $self->id($id);
$self->{'atom'} = [];
# the 'smallest' (and only) item that can be added to a residue is an atom
$atom && $self->throw("add atoms via an Entry object entry->add_atom(residue,atom)\n");
return $self;
}
=head2 atom()
Title : atom
Usage :
Function: nothing usefull untill I get symbolic references to do what I want
Returns :
Args :
=cut
sub atom {
my ($self,$value) = @_;
$self->throw("no code down here, go see an Entry object nearby\n");
}
=head2 add_atom()
Title : add_atom
Usage :
Function: nothing usefull untill I get symbolic references to do what I want
Returns :
Args :
=cut
sub add_atom {
my($self,$value) = @_;
$self->throw("nothing here, use a method on an Entry object\n");
}
=head2 chain()
Title : chain
Usage : $chain = $residue->chain($chain)
Function: Sets the Chain this Residue belongs to
Returns : Returns the Chain this Residue belongs to
Args : reference to a Chain
=cut
sub chain {
my($self, $value) = @_;
$self->throw("use an Entry based method please\n");
}
=head2 id()
Title : id
Usage : $residue->id("TRP-35")
Function: Gets/sets the ID for this residue
Returns : the ID
Args : the ID
=cut
sub id {
my ($self, $value) = @_;;
if (defined $value) {
$self->{'id'} = $value;
}
return $self->{'id'};
}
=head2 DESTROY()
Title : DESTROY
Usage :
Function: destructor ( get rid of circular references )
Returns :
Args :
=cut
sub DESTROY {
my $self = shift;
# no specific destruction for now
}
#
# from here on only private methods
#
=head2 _remove_atoms()
Title : _remove_atoms
Usage :
Function: Removes the atoms attached to a Residue. Tells the atoms they
don't belong to this Residue any more
Returns :
Args :
=cut
sub _remove_atoms {
my ($self) = shift;
$self->throw("no code here\n");
}
=head2 _remove_chain()
Title : _remove_chain
Usage :
Function: Removes the Chain this Residue is atttached to.
Returns :
Args :
=cut
sub _remove_chain {
my ($self) = shift;
$self->{'chain'} = undef;
}
=head2 _grandparent()
Title : _grandparent
Usage :
Function: get/set a symbolic reference to our grandparent
Returns :
Args :
=cut
sub _grandparent {
my($self,$symref) = @_;
if (ref($symref)) {
$self->throw("Thou shall only pass strings in here, no references $symref\n");
}
if (defined $symref) {
$self->{'grandparent'} = $symref;
}
return $self->{'grandparent'};
