The abstract factory pattern in software engineering is a design pattern that provides a way to create families of related objects without imposing their concrete classes, by encapsulating a group of individual factories that have a common theme without specifying their concrete classes. [1]
For example, several GoF patterns, like the Factory method pattern, the Builder or even the Singleton are implementations of this concept. The Abstract factory pattern instead is a method to build collections of factories. In some design patterns, a factory object has a method for every kind of object it can create
Design pattern, overview of design patterns in general; Abstract factory pattern, a pattern often implemented using factory methods; Builder pattern, another creational pattern; Template method pattern, which may call factory methods; Joshua Bloch's idea of a static factory method for which Bloch claims there is no direct equivalent in Design ...
Some examples of creational design patterns include: Abstract Factory pattern : a class requests the objects it requires from a factory object instead of creating the objects directly Factory method pattern : centralize creation of an object of a specific type choosing one of several implementations
Abstract factory: Provide an interface ... including the use of existing design patterns as well as domain-specific design patterns. Examples include user interface ...
Design patterns and their descriptions Pattern Description Singleton pattern: Ensures that a class has only one instance and provides a global point of access to it. Factory method pattern: Defines an interface for creating an object, but defers instantiation to subclasses. Abstract Factory pattern
In lobbying for a higher quality of life, for example, one of the top grievances raised by striking Starbucks workers was unpredictable scheduling, a popular practice in which employers don’t ...
A sample UML class and sequence diagram for the Abstract Factory design pattern. In the above UML class diagram, the Client class that requires ProductA and ProductB objects doesn't instantiate the ProductA1 and ProductB1 classes directly.
