=head1 NAME
Rose::DB::Object::ConventionManager::Null - A singleton convention manager that does nothing.
=head1 SYNOPSIS
package My::Product;
use Rose::DB::Object;
our @ISA = qw(Rose::DB::Object);
# This really sets the convention manager to a
# Rose::DB::Object::ConventionManager::Null object
__PACKAGE__->meta->convention_manager(undef);
...
=head1 DESCRIPTION
L<Rose::DB::Object::ConventionManager::Null> is a subclass of L<Rose::DB::Object::ConventionManager> that does nothing. That is, it overrides every method with no-ops that always return undef or an empty list, depending on calling context. This class is a singleton.
When a piece of L<metadata|Rose::DB::Object::Metadata> is missing, the convention manager is asked to provide it. This "null" convention manager class is useful if you do not want the convention manager to provide any information. In other words, use this convention manager class if you want to force all L<metadata|Rose::DB::Object::Metadata> to be explicitly specified.
See the L<Rose::DB::Object::ConventionManager> documentation for more information on convention managers.
