onや_onから始まるとthisで束縛するクラス

Class.ts

class Class {

  constructor() {
    var ctor:any = (<any>this).constructor;
    if (ctor.__on__ == null) {
      ctor.__on__ = {};
      for (var m in this) {
        var fn:any = this[m];
        if (typeof fn === 'function' &&
          (m.indexOf('on') === 0 || m.indexOf('_on') === 0)) {
          ctor.__on__[m] = fn;
        }
      }
    }
    for (var m in ctor.__on__) {
      ((m:string, fn:Function)=> {
        this[m] = ()=> {
          return fn.apply(this, Array.prototype.slice.call(arguments));
        };
      })(m, ctor.__on__[m]);
    }
  }

}

これでいい気がしてきた

export class Class {

  constructor() {
    for (var prop in this) {
      var fn = this[prop];
      if (typeof fn === 'function') {
        ((prop:string, fn:Function)=> {
          this[prop] = ()=> {
            return fn.apply(this, Array.prototype.slice.call(arguments));
          };
        })(prop, fn);
      }
    }
  }

}
