Why it is called IoC in spring?
When Spring tries to create an Employee object, it will see that Employee has a dependency on Address , so it will first create the Address object (dependent object) and then inject it into the Employee object. Inversion of Control (IoC) and Dependency Injection (DI) are used interchangeably.
What is difference between IoC and DI in Spring?
Inversion of control is a design principle which helps to invert the control of object creation. Dependency Injection is a design pattern which implements IOC principle. DI provides objects that an object needs.
What is the use of IoC?
The IoC container is a framework used to manage automatic dependency injection throughout the application, so that we as programmers do not need to put more time and effort into it. There are various IoC Containers for . NET, such as Unity, Ninject, StructureMap, Autofac, etc.
What is the definition of inversion of control?
inversion of control (IoC) is a programming technique, expressed here in terms of object-oriented programming, in which object coupling is bound at run time by an assembler object and is typically not known at compile time using static analysis. ~ http://en.wikipedia.org/wiki/Inversion_of_control
How does inversion of control reduce code duplication?
Inversion of control is a practical way to reduce code duplication, and if you find yourself copying an entire method and only changing a small piece of the code, you can consider tackling it with inversion of control. Inversion of control is made easy in many languages through the concept of delegates, interfaces, or even raw function pointers.
What does inversion of control from you to the cab driver mean?
Thus, this is called inversion of the control – from you to the cab driver. You don’t have to drive a car yourself and you can let the driver do the driving so that you can focus on your main work. The IoC principle helps in designing loosely coupled classes which make them testable, maintainable and extensible.
How does IOC invert the control flow in your program?
IoC not only inverts the control flow in your program, it also clouds it considerably. This means you can no longer just read your code and jump from one place to another because the connections that would normally be in your code are not in the code anymore.
