====== Simple Factory ====== 

====== Factory Method ======

UML Code (PlantUML)
<code>
@startuml
Product <|-- ConcreteProduct
Creator <|-- ConcreteCreator
ConcreteCreator ..> ConcreteProduct

class Creator {
  {abstract} fabricmethod()
  oneOperation()
}

class ConcreteCreator {
  fabricmethod()
}
@enduml
</code>

===== Advantages =====
  * No new operator is called by calling classes -> better to exchange implementation later
  * Better name for virtual constructor
===== Disadvantages =====
  * Creation of sub classes
  * Add. class which contains class method for creation necessary


====== Abstract Factory ======
