Programming - Template Behavioral Design Pattern

• AbstractClass
  and
  • defines abstract primitive operations that concrete subclasses define to implement steps of an algorithm
  • implements a template method defining the skeleton of an algorithm. The template method calls primitive operations as well as operations defined in AbstractClass or those of other objects.
• ConcreteClass
  • implements the primitive operations ot carry out subclass-specific steps of the algorithm

System;

namespace DoFactory.GangOfFour.Template.Structural
{

// MainApp test application

class MainApp
{
static void Main()
{
AbstractClass c;

c = new ConcreteClassA();
c.TemplateMethod();

c = new ConcreteClassB();
c.TemplateMethod();

// Wait for user
Console.Read();
}
}

// "AbstractClass"

abstract class AbstractClass
{
public abstract void PrimitiveOperation1();
public abstract void PrimitiveOperation2();

// The "Template method"
public void TemplateMethod()
{
PrimitiveOperation1();
PrimitiveOperation2();
Console.WriteLine("");
}
}

// "ConcreteClass"

class ConcreteClassA : AbstractClass
{
public override void PrimitiveOperation1()
{
Console.WriteLine("ConcreteClassA.PrimitiveOperation1()");
}
public override void PrimitiveOperation2()
{
Console.WriteLine("ConcreteClassA.PrimitiveOperation2()");
}
}

class ConcreteClassB : AbstractClass
{
public override void PrimitiveOperation1()
{
Console.WriteLine("ConcreteClassB.PrimitiveOperation1()");
}
public override void PrimitiveOperation2()
{
Console.WriteLine("ConcreteClassB.PrimitiveOperation2()");
}
}
}
