Prototype Pattern

  • Creational Pattern
  • The intent of this pattern is to specify the kinds of objects to create using a prototypical instance, and create new objects by copying this prototype.
  • Prototype:-  declares an interface for cloning itself.
  • Concreteprototype :- implements an operation for cloning itself.
  • Client:- creates a new object by asking a prototype to clone itself.
				
					namespace prototypepattern
{
    public interface  Person
    {
        public string Name { get; set; }
        public Person Clone();
    }

    public class Manager : Person
    {
        public  string Name { get; set; }

        public Manager(string name)
        {
            Name = name;
        }

        public Person Clone()
        {
            return (Person)MemberwiseClone();
        }
    }

    public class Employee : Person
    {
        public string Name { get; set; }
        public Manager Manager { get; set; }
        public Employee(string name, Manager manager)
        {
            Name = name;
            Manager = manager;
        }
        public Person Clone()
        {
            return (Person)MemberwiseClone();
        }
    }
