What is used in abstract factory pattern?
Abstract Factory provides interfaces for creating families of related or dependent objects without specifying their concrete classes. Client software creates a concrete implementation of the abstract factory and then uses the generic interfaces to create the concrete objects that are part of the family of objects.
Which data structure is more efficient for in memory text file viewer?
Splay Tree Although a tree-like data structure will have decent efficiency, it can still be more optimized for text editors.
What is file system in data structure?
There are two important data structures used to represent information about a virtual file system, the vfs structure and the v-node. Each virtual file system has a vfs structure in memory that describes its type, attributes, and position in the file tree hierarchy.
What is abstract class in design pattern?
Abstract Factory Pattern says that just define an interface or abstract class for creating families of related (or dependent) objects but without specifying their concrete sub-classes. That means Abstract Factory lets a class returns a factory of classes. An Abstract Factory Pattern is also known as Kit.
What do you call an abstract factory pattern?
This factory is also called as factory of factories. This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object. In Abstract Factory pattern an interface is responsible for creating a factory of related objects without explicitly specifying their classes.
What is a factory in a design pattern?

How are abstract factories used in client software?
Client software creates a concrete implementation of the abstract factory and then uses the generic interfaces to create the concrete objects that are part of the family of objects. The client does not know or care which concrete objects it gets from each of these concrete factories since it uses only the generic interfaces of their products.
How is an interface used in a factory pattern?
In Abstract Factory pattern an interface is responsible for creating a factory of related objects without explicitly specifying their classes. Each generated factory can give the objects as per the Factory pattern. We are going to create a Shape interface and a concrete class implementing it.
