What are static factory methods?
All static factory methods have been replaced with standard reusable Zend Framework factory classes.
Factory method in UML and in LePUS3(a Design Description Language) Consider static factory methods by Joshua Bloch.
How to implement the factory method pattern in C++ correctly.
The factory method pattern relies on inheritance, as object creation is delegated to subclasses that implement the factory method to create objects.[3].
A sample UML class diagram for the Factory Method design pattern.
A factory method is just an addition to Factory class. It creates the object of the class through interfaces but on the other hand, it also lets the subclass decide which class is instantiated.
The most convenient-ready panel with seam and groove glued factory method, as shown in the photo.
The Factory Method[1] design pattern is one of the"Gang of Four" design patterns that describe how to solve recurring design problems to design flexible and reusable object-oriented software, that is, objects that are easier to implement, change, test, and reuse.
In the HTML5 DOM API,the Document interface contains a createElement factory method for creating specific elements of the HTMLElement interface.
The Factory Method design pattern is used instead of the regular class constructor for keeping within the SOLID principle of programming, decoupling the construction of objects from the objects themselves. This has the following advantages and is useful for the following cases, among others:[2].
Room is the base class for a final product(MagicRoomor OrdinaryRoom). MazeGame declares the abstract factory method to produce such a base product. MagicRoom and OrdinaryRoom are subclasses of the base product implementing the final product.
You can see we have used MakeProduct in concreteFactory. As a result, you can easily call MakeProduct() from it to get the IProduct. You might also write yourcustom logic after getting the object in the concrete Factory Method.
Define an interface for creating an object,but let subclasses decide which class to instantiate. The Factory method lets a class defer instantiation it uses to subclasses."(Gang Of Four).
The Factory Method design pattern is used by first defining a separate operation, a factory method, for creating an object,and then using this factory method by calling it to create the object. This enables writing of subclasses that decide how a parent object is created and what type of objects the parent contains. See the UML class diagram below.
For example, a Vehicle can be prevented from being instantiated directly since it has no constructor, and only subclasses like ElectricPlane orOldCar can be created by calling the Vehicle(static) factory method in the subclass constructor or initializer.
In the above snippet, the MazeGame constructor is a template method that makes some common logic.It refers to the makeRoom factory method that encapsulates the creation of rooms such that other rooms can be used in a subclass. To implement the other game mode that has magic rooms, it suffices to override the makeRoom method: .
Creating an object directly within the class that requires or uses the object is inflexible because it commits the class to a particular object and makes it impossible to change the instantiation independently of the class. A change to the instantiator would require a change to the class code which we would rather not touch.This is referred to as code coupling and the Factory method pattern assists in decoupling the code.
IDbCommand. CreateParameter is an example of the use of factory method to connect parallel class hierarchies. In Qt,QMainWindow::createPopupMenu is a factory method declared in a framework that can be overridden in application code. In Java, several factories are used in the javax. xml. parsers package. e.g. javax. xml. parsers. DocumentBuilderFactory or javax. xml. parsers.
Another example in PHP follows, this time using interface implementations as opposed to subclassing(however the same can beachieved through subclassing). It is important to note that the factory method can also be defined as public and called directly by the client code(in contrast with the Java example above).
For example, a class Vehicle with a member Motor defined with a dynamic type, can have subclasses of type ElectricPlane and OldCar each constructed with a different type of Motor.This can be accomplished by constructing the subclasses with a Vehicle factory method, while supplying the motor type. In cases like this the constructor may be hidden.
Thus, for example, a class Vehicle that has a member Motor of interface IMotor, but no concrete type of Motor defined in advance, can be constructed by telling the Vehicle constructor to use an ElectricMotor or a GasolineMotor.The Vehicle constructor code then calls a Motor factory method, to create the desired Motor that complies with the IMotor interface.
