=head1 METHODS
|
|
|
|
The available methods are those inherited from the base class augmented
|
|
by the type-specific methods defined in this package.
|
|
|
|
Use of undocumented package features or direct access to internal data
|
|
structures is discouraged and could result in program termination or
|
|
other unpredictable behaviour.
|
|
|
|
|
|
=head2 cname

|
|
|
$cname = $rr->cname;
|
|
$rr->cname( $cname );
|
|
|
|

|
|
the owner. The owner name is an alias.
