import {Factory, Directive, Provider, Service, Controller} from 'ng-decorators'

@Factory(['$window'])  //or Directive or Provider or Service or Controller
class FooBar{
  constructor(win){ //if you need to access the injected object it will be passed into the constructor
    console.log(win.location.host)
  }

  logOrigin(){
    console.log(this.$window.origin); //all the injected values will be auto injected to the class under this.<injected object>
  }
}

app.factory('FooBarService', FooBar);
// or app.directive('FooBarService', FooBar);
// or app.service('FooBarService', FooBar);
