 | Prototype Design Pattern
The prototype design pattern is a design pattern that is used to instantiate a class by copying, or cloning, the properties of an existing object. The new object is an exact copy of the prototype but permits modification without altering the original. |
| Abstract Factory Design Pattern
The abstract factory pattern is a design pattern that allows for the creation of groups of related objects without the requirement of specifying the exact concrete classes that will be used. One of a number of factory classes generates the object sets. |
| Factory Method Design Pattern
The factory method pattern is a design pattern that allows for the creation of objects without specifying the type of object that is to be created in code. A factory class contains a method that allows determination of the created type at run-time. |
| Singleton Design Pattern
The singleton pattern is a design pattern that is used to ensure that a class can only have one concurrent instance. Whenever additional objects of a singleton class are required, the previously created, single instance is provided. |
