Prototype Class

Giovanny Gongora

Prototype is a creational design pattern that lets you copy existing objects without making your code dependent on their classes.

export interface Prototype {
  clone(): Prototype;
  toString(): string;
}
export class Concrete1 implements Prototype {
  clone() : Prototype {
    return new Concrete1();
  }
  toString(): string {
    return "This is Concrete1";
  }
}
export class Builder {
  private prototypeMap: { [s: string]: Prototype; } = {};
  constructor() {
    this.prototypeMap['c1'] = new Concrete1();
  }
  createOne(s: string): Prototype {
    console.log(s);
    return this.prototypeMap[s].clone();
  }
}
