Function

reopenClass public

Module:	@ember/object

Defined in packages/@ember/-internals/runtime/lib/system/core_object.js:810

Augments a constructor's own properties and functions:

import EmberObject from '@ember/object';

const MyObject = EmberObject.extend({
  name: 'an object'
});

MyObject.reopenClass({
  canBuild: false
});

MyObject.canBuild; // false
o = MyObject.create();

In other words, this creates static properties and functions for the class. These are only available on the class and not on any instance of that class.

import EmberObject from '@ember/object';

const Person = EmberObject.extend({
  name: '',
  sayHello() {
    alert(`Hello. My name is ${this.get('name')}`);
  }
});

Person.reopenClass({
  species: 'Homo sapiens',

  createPerson(name) {
    return Person.create({ name });
  }
});

let tom = Person.create({
  name: 'Tom Dale'
});
let yehuda = Person.createPerson('Yehuda Katz');

tom.sayHello(); // "Hello. My name is Tom Dale"
yehuda.sayHello(); // "Hello. My name is Yehuda Katz"
alert(Person.species); // "Homo sapiens"

Note that species and createPerson are not valid on the tom and yehuda variables. They are only valid on Person.
