Creational design patterns

• Abstract Factory - an instance of several families of classes
• Builder - object construction from its representation
• Factory Method - an instance of several derived classes
• Object Pool - expensive acquisition and release of resources by recycling objects that are no longer in use
• Prototype - fully initialized instance to be copied or cloned
• Singleton - class of which only a single instance can exist

Structural design patterns
