Abstract factory pattern implementation provides us a framework that allows us to create objects that follow a general pattern. Free source code and UML. Abstract Factory Design Pattern Video Java Implementation in Tamil. But the code quickly becomes cumbersome if I ask you to add support for more beverages. You have different data storage mechanisms like relational database, Xml format file storage & Object storage which can store customer & account data in different format but exposes them in the same way to the client. If the third kind of input is sent, it will return null only. And the code is not maintainable either. All other patterns… After a lot of search and study, I endeavored to find an actual need for the abstract design pattern. Typically, when the underlying implementations or mechanisms of object creation vary a lot but those implementations can be placed under the same top level umbrella & you need same public API to access them, there is a good chance that you need Abstract Factory Method design pattern. a family … I did not use much theoretical terms in the explanation, rather kept it as much as practical as possible. Customization & Preparation are sample generic objects showing what can be the possible customization parameters & overall ingredients in the system across products. Ok! This is just unmaintainable. The second statement “FactoryCreator.getSourceCourseFactory”. Note that only the respective factories know how to create connection to the underlying data storage & how to communicate with them. The “Source” interface consists of a solo abstract method called “public String getSource”. If we send “Source.getCourse” as input, it will return null because here the implementation for “getCourse” is returning null. Abstract Factory Design Pattern Video in Tamil. Factory Design Pattern in C# with Real-Time Example. ; It provides an interface for creating families of related or dependent objects without specifying their concrete classes. Abstract Factory Design Pattern Video Java Implementation in Telugu. We are broadly dealing with beverage products, but their nature & ingredients are fundamentally different. Also there is a static method getProductFactory() which facilitates the discovery of factories to the client. All of the mentioned products implement make() method which will be invoked by the caller to finally prepare the product. Two objects from different group can not be mixed. “SourceCourseFactory” consists of two abstract methods,”getSource” and “getCourse”. If you have reached this much, please share this article so that other people also benefit. But is it right to do so? Storing these parameters might not be required at all, depends on your use case. In this article, I am going to discuss the Factory Design Pattern in C# with examples. Since the implementation for “getSource” is returned null. Abstract Factory Design Pattern Video in Telugu. It provides an interface for creating families of related or dependent objects without specifying their concrete classes. Even if we call “course.getSource” of some input, it will return null. Example. C# Design Patterns. ... At this point in time, ... there is a good chance that you need Abstract Factory Method design pattern. Try to see if you already have same sort of use cases & how to map them to this design approach. But notice one thing — even if you are supporting Coffee only, different variants of coffee may have different ingredients. Coffee products Cappuccino, BlackCoffee, juice product like Lemonade, Coke product like CocaCola, other products like HotMilk — all implements the Product interface because as per the assumption of our system, we are creating different products with the same interface for the end user. Each dedicated factory like RdbDAOFactory can create both DAO implementations like RdbDAO1 & RdbDAO2 etc. Indeed, most patterns make the code more difficult to understand. In order to better understand, look at the hierarchy above, as explained try to figure out in your mind why different factories were created, how different setter methods are not used outside the factory, how the full abstraction is created & in which scenario this abstraction is applicable. These objects have some meanings in group. We have a Product interface which is the super type of the end product that we are expecting from the system. ... at a real world example to help our understanding a little more. The abstract factory pattern provides a way to encapsulate a group of individual factories that have a common theme without specifying their concrete classes. Abstract Factory pattern is “factory of factories” and can be easily extended to accommodate more products, for example we can add another sub-class Laptop and a factory LaptopFactory. If the requirements for this “Animal Factory” is that “I need a wild animal. The implementer classes for “Source” are “offline” and “online”. The programming world has encountered a large number of problems, and a variety of solution have been proposed to tackle them. While learning design patterns, I came to understand the most frequently used term, Factory Pattern as well as Abstract factory pattern. In my previous article, we covered Factory Method Design Pattern In C#. If we send “Course”, it will analyze this input and return “CourseFactory” object. This “FactoryCreator” is the “abstract factory” for this application. The above videos are in Tamil and Telugu languages also. In the above code snippet, the caller of the above getCoffee() method may set different quantity of milk, sugar, water etc after getting an instance of the coffee. So the design should be extensible. This means that whenever you buy a product on Amazon from a link on here, we get a small percentage of its price. Each abstract product (chair/sofa) must be implemented in all given variants (Victorian/Modern). Basically you have put all the object creation logic related code in this factory & it does more than one thing. Happy Learning!! If we give any other input means it will return the null. Concrete Products are various implementations of abstract products, grouped by variants. How would you design that? These methods are very product specific method which are needed for setting the right amount of ingredients. Remember, going forward you may be asked to add support for say fruit juice, tea or some variety of milk shake, chocolate shake etc. Using that “online” object, we are calling “getSourceName”. All the source code for this post available on Github Repo . So now your coffee creation code looks something like below: See the above code block. This post is not about designing the complete vending machine, rather it discusses only one portion of the machine — how to support different variants of beverages, customers will browse all product & choose any one as per their choice. Let’s see what this modelling offers to us. In our scenario, we are supporting actually different products but all are broadly defined as beverage products at least for the customer. The client can order two Brand Laptop, Apple and Dell with variable storage size. This pattern is found in the sheet metal stamping equipment used in the manufacture of Japanese automobiles. Example — add support for coke, coke can be mixed with water or soda, but not with milk or coffee powder. Let’s see what this modelling offers to us. Here using Document Builder, I am getting the concrete objects for docFact” object. And it will try to return the appropriate object for the criteria which would be a “lion”. Abstract factory design pattern is used to mange different object types of same family. Abstract Factory Design Pattern in C# with Real-Time Example. So, the implementation for “getSource” will return null. Hope both the examples clear your concept about Abstract Factory Method pattern & most importantly when to use them. It should be easy to change formula of any of the beverages. This is how abstraction for heterogenous objects are created by Abstract Factory Method. The first class will return “Java” because it’s related to programming and the second class will return “DSP” because it’s related to non-programming. And your switch case block has to be modified again. The client / caller does not need to pay any heed to such internals. These two classes will be handled by the “Course” Factory based on the “courseType”, it will return the better object. Some Real world example with database Can you pls provide me any good example of Abstract Factory pattern used in a project within database interaction. The following is another very good use case of Abstract Factory Method borrowed from a Oracle documentation which shows how to model data access strategy if your client is only exposed to very specific DAO interfaces, but you have multiple data storage implementation available which can offer data access through the same interface. The legs of that animal should be four, and the weight should be less than 4kg.”. So we are dealing with runtime polymorphism for sure but at the same time the instantiation logic or parameter setting logic are completely different from each other. Google Kubernetes Engine Logging by Example, 5 Programming Projects to Get you Through the Darker Months, How to use Python Lambda functions: a 5-Minute Tutorial, Understanding Arrow Functions in JavaScript. Example: Lemonade is instantiated by LemonadeFactory. 2. You can already look deeper into different real time examples of abstract factory in JDK distribution: DocumentBuilderFactory#newInstance() TransformerFactory#newInstance() There are other similar examples but the need is to have the feel of the abstract factory design pattern, which you must have got till now. Probably you would start with defining some coffee type enums & creating coffee objects in a if-else or switch statements or wrap this whole object creation logic in a factory, if you don’t know what a factory pattern is, please look at this post & understand that first. Moreover, if you need to add support for say tea, the factory has to know how to create tea & how to set its ingredients as well. A New Way To Trade Moving Averages — A Study in Python. The “Light Fever” factory will return the appropriate medicine, in this case. The purpose of the Abstract Factory is to provide an interface for creating families of related objects, without specifying concrete classes. Simple Factory: Strictly speaking, it’s not a design pattern, but a technique we use very often.It encapsulates the object instantiation process. Similarly CocaCola has setCoke() while others don’t have that. It falls under the Creational Design Pattern. For medium to large projects involving multiple developers using the same code I find them useful. Currently you have assumed all formula to be constant but the owner of the vending machine does not want to set any constant formula in the machine, rather he has his own server where formula are hosted & he wants to fetch from there probably because the formula is a secret formula & he does not want anyone to view those formula. it’s a little better approach. So at runtime, abstract factory is coupled with any desired concrete factory which can create objects of desired type. In other word we can say that we have some objects and they are grouped. The instantiation logic is concentrated in the factory, so if you need to remove some existing implementation, remove the product & the factory. In this case, we are calling, “course.getCourse” programming. Abstract Factory is one of the key patterns and it falls under the creational segment. Abstract Factory is a creational design pattern, which solves the problem of creating entire product families without specifying their concrete classes.. Abstract Factory defines an interface for creating all distinct products but leaves the actual product creation to concrete factory classes. In this post, we have learned the Factory Pattern from Head First Design Patterns book. If you need to add a new product first check if any of the existing product & factory can be used to support that new product without much change, otherwise add new product & factory — no change is required in much of the existing code, only probably you need to add a switch case in the. Since we are sending “course” as input this “FactoryCreator” it will return “CourseFactory” object. If there’s a medical representative and I am the customer. Here’s another example. Each of the objects additionally stores what preparation & customization parameters were passed while creating those objects in prep & cust instance members respectively. Design Patterns: Learning Abstract Factory Method through real life examples. Though this article is about factory patterns, using patterns just for using patterns is worst than never using them. Structural code uses type names as defined in the pattern definition and UML diagrams. The Abstract Factory Pattern is a creational Gang of Four (GoF) design pattern, defined in their seminal book Design Patterns: Elements of Reusable Object-Oriented Software, in which they presented a catalogue of simple and succinct solutions to commonly occurring design problems. This main program will use the abstract factory for getting the factory objects. Most of the time, I don’t use factories. ... You can find an example on our Singleton pattern page. Say the problem statement only asks you to design a coffee vending machine which can provide you with different variants of coffee like — Espresso, Latte, Cappuccino, Black Coffee etc. How will you support those scenarios in your code? Real World Example Implementation of Abstract Factory Design Pattern Let’s consider a scenario where a Laptop dealer (Client) buy a Laptop (Product) as per customer need. All the factories extends DAOFactory abstract super class which is used by the client / caller to get a very specific factory instance & then access their corresponding DAO objects. Abstract Factory patterns work around a super-factory which creates other factories. Only the factory knows how to instantiate the product, what quantity of ingredients to set, this abstracts out the product creation & parameter setting logic from the caller — caller does not need to care about how to create products, caller delegates the task of object creation to the factory & the factory does all the hard work. Moving right along through our Guide to Software Design Patterns, today we’re going to take a deeper dive into the next Creational design pattern on the list: the abstract factory.The abstract factory is the final factory pattern we’ll be exploring in this series and, perhaps unsurprisingly, it is the most robust and detailed of all three factory patterns we’ll be covering. You need to modify the same code again & again. If the input is online, it will return the “online” object. Using that “sourceFactory” object, we can call two methods. ProductFactory is an abstract class that defines the contract all factories which are responsible for product creation should implement. They are Domestic and Wild. Abstract Factory might store a set of Prototypes from which to clone and return product objects. Consider another scenario, what if I say the DEFAULT values that are defined above should come from different configuration file or data source or different service? Create Factory classes extending AbstractFactory to generate object of concrete class based on … Any thoughts, let me know in the comments please. 3. Factory Method Pattern. the system is or should be configured to work with multiple families of products. If the requirements are 4 legs and 50 kg, the appropriate object would be a “lion” or a “tiger”, it depends. The “Domestic Animal” factory would manage these classes. All the object should belong to same family but they are of different categories. Please read our previous article where we discussed the Factory Method Design Pattern in C# with an example. Cat and Dog belong  under domestic category and Lion and Tiger belong under the wild category. The Factory Method Pattern is also known as Virtual Constructor. In this article, we will cover another software design pattern in C# application development, Abstract Factory.Abstract Factory pattern also falls under Creational Pattern of Gang of Four (GoF) Design Patterns.Background Before talking about Abstract Factory pattern, I just want to share a little about \"Gang of Four (GoF)\" to which the Abstract Factory pattern belongs. This is just a plain violation of Single Responsibility Principle. Example: Black Coffee might not require sugar, it only requires coffee powder, water or milk. Factory Method: creation through inheritance. It abstracts the client from knowing which factory would be returned. Abstract Factory Design Pattern Video in English. In this example also you have multiple implementations which are instantiated by their corresponding factories but they all serve the same purpose to the client — exposing DAO1 & DAO2 operations. There’s the main class and an interface called “Course”.This course has an abstract method “public String getCurseName.””ProgramminCourse” and “NonprogrammingCourse” are the two classes which implement that interface. In normal usage, the client software creates a concrete implementation of the abstract factory and then uses the generic interface of the factory to create the concrete objects that are part of the theme. So the input for this type will be “source”. When to use Abstract Factory Design Pattern? This factory also extends “SourceCourse” factory, that’s the reason why we have implemented two methods. You can watch these videos on YouTube by clicking the below links. Using that actual factory you can get the concrete objects. There is a separate post for Factory Pattern in detail with examples, advantages, real-world examples. The “SourceFactory will handle these classes”.It will return the best object based on the input. In this article, I am going to discuss the Abstract Factory Design Pattern in C# with an example. An attempt was made by a group of four people, famously called the “Gang-Of-Four” or GoF, to come up with a set of common problems and solutions for them, in the given context. All of those have four legs so it will try to return the animals with four legs. The advantage of the approach is: Note: It’s not mandatory to create a factory for each product, if you have multiple products which can be created with same setter methods (same preparation materials), which only vary in terms of quantity of ingredients, they can be created through a single factory. When I code alone at home/work, I avoid using them. Instead, inside the switch-case block itself, you can set those parameters while creating an instance. Cool! Let’s remodel the vending machine as shown in the image below. Abstract Factory patterns is a super factory which will return the best Factory based on the input. For small projects that won’t change a lot I also avoid factories. Here the course will be “programming” it would return “ProgrammingCourse”.Using that object, we are calling “getCourseName”.So  programming “course.getName” is returned Java. The stamping equipment is an Abstract Factory which creates auto body parts. introduces loose coupling between classes which is the most important principle one should consider and apply while designing the application architecture As mentioned caller does not care how the products are created. It will return “sourceFactory” object. Abstract Factory patterns is a super factory which will return the best Factory based on the input. The “getSource” will return the actual source objects based on the input while “getCourse” will return only null because the “source factory” doesn’t consist of anything related to “Course”. A Factory Pattern or Factory Method Pattern says that just define an interface or abstract class for creating an object but let the subclasses decide which class to instantiate. Abstract Products declare interfaces for a set of distinct but related products which make up a product family.. So coke has completely different set of ingredients. If we send “Source”, it will analyze the data and return “Sourcefactory” object. Say default values or formula of coffee preparation comes from service 1 & formula of coke comes from service 2. This behaviour is an anti-pattern. Change is constant & inevitable, you have to always change something in your code, but how to minimize that change? As you know that the design patterns have three categories named creational, structural and behavioral respectively. Animals are classified into two group types. Abstract Factory Design Pattern: * It falls under Creational Design Pattern. How will you accommodate those changes in the above code? The pattern allows us to do so by enforcing the desired family of products to be at the same time. References: source. The Factory Design Pattern is one of the most frequently used design patterns in real-time applications. www.programmingline.com participates in the Amazon Associates Associates Program, an affiliate advertising program designed to provide a means for sites to earn commissions by linking to Amazon. Abstract Factory - Free .NET Design Pattern C#. Abstract Factory Design Pattern Benefits Abstract Factory design pattern provides approach to code for interface rather than implementation. How do you write your code in such a way that your changes are always minimum. Whenever you need to write some object creation logic, try to see if this pattern fits your use case, don’t try to fit forcefully, that will break the whole purpose of using design patterns. I always think of fa… It does multiple things — it knows how to create objects & how to set their respective parameters. Under beverage umbrella, they belong to different kind of categories like Black Coffee belongs to Coffee category, CocaCola belongs to Coke category, Orange / Mango juice belongs to juice category etc. Factory Method: Defines an interface for creating an object, but let’s the classes that implement the interface decide which class to instantiate.The Factory method lets a class defer instantiation to subclasses. Similarly, the “Wild Animal” factory will return the appropriate object based on the requirements. I ask that medical representative about the medicines for fever and cold problems. We have been building object-oriented software for over 40 years now, starting with Smalltalk, which was the first object-oriented language. Such different category objects creation under the same umbrella is supported by Abstract Factory Method. For example, if a customer goes to a “Domestic Animal” factory and he requests animals with four legs and weight of 25kg. If you send any sourceType object, it will return null only. I searched the internet and came across numerous learning points. This is helpful when an object needs to be created from a family of classes. Here, say DAO1 exposes some customer entity related operations like find, create etc, DAO2 exposes their bank account related operations. Hypothetical scenario but quite possible in some form or the other. In other words, subclasses are responsible to create the instance of the class. UML Diagram of Abstract Factory Design Pattern, Java Implementation of Abstract Factory Design Pattern, Tutorial video of Abstract Factory Design Pattern. Applicability & Examples We should use the Abstract Factory design pattern when: the system needs to be independent from the way the products it works with are created. The category “Animal” is an interface. One is “getSource” one is “getSource”. Using this factory, you can get the actual factory object that is getinstance” method. Products . These are the three requirements based on which the “Animal Factory” would try to return the appropriate factory. How will you support that? The outside world is uncertain if it is a wild animal or domestic animal factory. At this point in time, you are probably considering to create an object of type Customization which contains different fields like — milk, water, soda, sugar etc and pass it to your factory or switch-case block. Abstract Factory Design Pattern in Java Back to Abstract Factory description Abstract Factory classes are often implemented with Factory Methods, but they can also be implemented using Prototype. I know there are many articles available for Abstract Factory Pattern but my goal is to explain this concept with a simple and real-world example. So using this “CourseFactory” object, we can call two methods “course.getCourse” and then “course.getSource”. The Abstract Factory interface declares a set of methods for creating each of the abstract products. If we send programming, it will return “ProgrammingCourse” object, on the other hand, if we send non-programming, it will return the “NonprogrammingCourse” object. The “Animal” factory will manage these two factories. The above approach works. Your current design does not support that. Notice how the setter methods of all the product vary: Cappuccino & BlackCoffee have setMilk() method while Lemonade & CocaCola don’t have them. The factory would return the dog object as it will be more appropriate than the cat. Abstract Factory Design Pattern Video Java Implementation in English. Based on the requirements, it will try to choose the “Light Fever” factory or “Heavy Fever” factory. Real-world code provides real-world programming situations where you may use these patterns. The “Animal” factory would be abstract to the outside world. You have to design a generic vending machine which can provide you different variants of Coffee, Hot Water, Hot Milk, Coke, Lemonade & what not. This tutorial highlights implementing the abstract factory design pattern in your Java projects, focusing on implementation, structure, and helpful examples. Real-world code in C#. Should the caller care about instantiation logic of the coffee objects? To give you a head start, the C# source code for each pattern is provided in 2 forms: structural and real-world. It will return “Books” for “offline” and “Youtube” for “online”. In other words, this model allows us to create objects that follow a general pattern.An example of the Abstract Factory design pattern in the JDK is the new… The client should be independent of how objects are created and for which class object is created. This “FactoryCreator” will return the best factory object based on the input. For example: 1. More beverages you add, more code you add or modify in the above code segment. The “CourseFactory” only involves the “getCourse” details. Here, the appropriate factory would be “Wild animal” factory. * It provides an interface for creating families of related or dependent objects without specifying their concrete classes. Since the input for this sourceType is “online” so it will return online object. There are two factories “Course” factory and “Source” factory. If it is offline, it will return the “offline” object. So, using concrete objects, we can do any number of operations. Let’s suppose; if you are trying to read some XML files using Dom parser, you will use Abstract Factory because Document Builder Factory is an Abstract Factory. In this article, we'll discuss the Abstract Factory design pattern.The book Design Patterns: Elements of Reusable Object-Oriented Software states that an Abstract Factory “provides an interface for creating families of related or dependent objects without specifying their concrete classes”. Each of the products are instantiated inside its own factory. Let see the GOFs representation of Abstract Factory Pattern : UML class diagram … What ingredients to use, how to fetch the ingredients formula, how to calculate their right quantity — all the things are taken care of by the factory. Let’s remodel the vending machine as shown in the image below. What if I say that a customer can customize the beverage — s/he might choose whether s/he needs sugar or not — how much quantity of sugar, whether s/he needs mix up of water & milk in the coffee or not, or whether s/he needs soda in coke or not. So “online” object is Youtube. Real-time Examples of Abstract Factory Design Pattern. Similarly other variants of coffee might differ in terms of percentage of ingredients like say the same quantity of Cappuccino may need more coffee powder than the same quantity of Latte.
