If your constructor is called +with an attribute that your class does not declare, then it calls +"Carp::confess()". This is a great way to catch small typos. + +=head2 Subverting Strictness + +You may find yourself wanting to accept a parameter to the constructor +that is not the name of an attribute. + +In that case, you'll probably be writing a C method to deal +with it. Your C method will receive two parameters, the new +object, and a hash reference of parameters passed to the constructor. + +If you delete keys from this hash reference, then they will not be +seen when this class does its checking. + + sub BUILD { + my $self = shift; + my $params = shift; -This class provides the following methods + if ( delete $params->{do_something} ) { + ... + } + } =head1 AUTHOR @@ -56,10 +81,11 @@ Dave Rolsky, C<< >> =head1 BUGS -Please report any bugs or feature requests to C, -or through the web interface at L.
