Difference between abstract factory pattern and factory
method pattern in .NET with example.
Answer Posted / guest
Abstract Factory patterns acts a super-factory which creates
other factories. This pattern is also called as Factory of
factories. In Abstract Factory pattern an interface is
responsible for creating a set of related objects, or
dependent objects without specifying their concrete classes.
public interface AbstractFactory
{
AbstractProductA CreateProductA();
AbstractProductB CreateProductB();
}
public class ConcreteFactoryA : AbstractFactory
{
public AbstractProductA CreateProductA()
{
return new ProductA1();
}
public AbstractProductB CreateProductB()
{
return new ProductB1();
}
}
public class ConcreteFactoryB : AbstractFactory
{
public AbstractProductA CreateProductA()
{
return new ProductA2();
}
public AbstractProductB CreateProductB()
{
return new ProductB2();
}
}
public interface AbstractProductA { }
public class ProductA1 : AbstractProductA { }
public class ProductA2 : AbstractProductA { }
public interface AbstractProductB { }
public class ProductB1 : AbstractProductB { }
public class ProductB2 : AbstractProductB { }
public class Client
{
private AbstractProductA _productA;
private AbstractProductB _productB;
public Client(AbstractFactory factory)
{
_productA = factory.CreateProductA();
_productB = factory.CreateProductB();
}
}
