DesignPattern::Factory - Perl implementation of the Factory Method.
This group of modules implement the Factory Method as described in Gamma E, et al. 'Design Patterns: elements of reusable object-oriented software' Addison-Wesley, 1995 [known to many as GOF].
The Factory Method's intent is to 'Define an interface for creating an object, but let subclasses decide which class to instatiate. Factory Method lets a class defer instantiation to subclasses.' [GOF, p107]
Fuller documentation is available in each of the participating classes, named:
DesignPattern::Factory::Product DesignPattern::Factory::ConcreteProduct DesignPattern::Factory::Creator DesignPattern::Factory::ConcreteCreator
A good place to start reading the documentation is DesignPattern::Factory::ConcreteCreator, which in a real-world example would be your application.
