in reply to OO: Building an object of the right type based on a parameter

Class::Factory allows you to decouple these things -- you can map a name/type to a class name and initialize a factory with them, then call 'new' on the factory and pass it the name/type and get back an object of the right type.

Here's an example, untested. (See the docs for more.)

package InvoiceCalculatorFactory; use base qw( Class::Factory ); __PACKAGE__->add_factory_type( old_school => 'InvoiceCalculator::OldSchool' ); __PACKAGE__->add_factory_type( new_school => 'InvoiceCalculator::NewSchool' ); __PACKAGE__->add_factory_type( delinquent => 'InvoiceCalculator::Delinquent' );

And then, assuming your client object has a field 'type' or something, you can do:

my $calculator = InvoiceCalculatorFactory->new( $client->type );

Good luck!
