Class ImplementableAbstract

Abstract class serving as a base for interface-like pure abstract classes that work with the "instanceof"-operator.

Usage:

• Create a pure abstract class that extends Implementable that will serve as your interface. Specify the required attributes and methods within it as abstract.
• Use your abstract class via the implements keyword exactly how you would use a regular interface.
• Decorate the class that implements your abstract class using the static YOUR_ABSTRACT_CLASS.register method.
• Now you can use the instanceof-operator with your abstract class.

Example:

import ƒ = FudgeCore;

abstract class MyInterface extends ƒ.Implementable {
  public abstract myAttribute: string;
  public abstract myMethod(): void;
}

@MyInterface.register
class MyClass implements MyInterface {
  public myAttribute: string;
  public myMethod(): void {}
}

let myInstance: MyInterface = new MyClass();
console.log(myInstance instanceof MyInterface); // true
console.log(MyClass.prototype instanceof MyInterface); // true
