Prototype pattern

Comments

This pattern creates the kind of object using its prototype. In other words, while creating the object of Prototype object, the class actually creates a clone of it and returns it as prototype.You can see here, we have used MemberwiseClone method to clone the prototype when required.

Code

{
        // normal implementation
        public abstract Prototype Clone();
    }

    public class ConcretePrototype1 : Prototype
    {
        public override Prototype Clone()
        {
            return (Prototype)this.MemberwiseClone(); // Clones the concrete class.
        }
    }

    public class ConcretePrototype2 : Prototype
    {
        public override Prototype Clone()
        {
            return (Prototype)this.MemberwiseClone(); // Clones the concrete class.
        }
    }
