When to use abstract factory pattern in IOC?
When it comes to IoC, one use of the abstract factory pattern is for abstacting the new operator out of the rest of the code to isolate it, making it DI friendly. This makes it loosely coupled from the code that uses the factory.
What is the factory pattern for dependency injection?
By using dependency injection we move the creation and binding of the dependent objects outside of the class that depends on them. Thus, solving the problems that we face with hardcoded dependency and making the classes loosely coupled. What is Factory Pattern?
How are design patterns used in software design?
Software Design Pattern: Software Design Patterns are a general reusable solution to a commonly occurring problem within a given context in software design. These are common solutions for object-oriented programming problems. Like the Singleton Pattern and Factory Pattern.
Which is the best definition of a factory pattern?
The Factory Pattern is a Design Pattern which defines an interface for creating an object but lets the classes that have a dependency on the interface decide which class to instantiate.
Why do you need IoC container in concrete factory?
First, you have a concrete factory, an IoC container could be an alternative rather than something to help you there. Then, just refactor the factory to not to expect a full possible parameter list in the factory constructor. This is the primary issue – why are you passing so many parameters if the factory method doesn’t need them?
Is it easy to use poor man’s di with IOC containter?
Like you wrote, it’s not easy to use if mixed with IOC containter. However in some case a similar approach ( poor man’s DI) can be useful. All in all, I wouldn’t bother having “many” dependencies in your factories. It’s a simple, declarative code. It takes seconds to write and can save you hours of struggling with runtime errors.
Is it possible to use service locator with IOC containter?
It’s actually a service locator, which is considered an anti-pattern. Like you wrote, it’s not easy to use if mixed with IOC containter. However in some case a similar approach ( poor man’s DI) can be useful. All in all, I wouldn’t bother having “many” dependencies in your factories. It’s a simple, declarative code.
