Function
reopenClass public
Module: | @ember/object |
---|
Defined in packages/ember-runtime/lib/system/core_object.js:753
Augments a constructor's own properties and functions:
const MyObject = Ember.Object.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.
const Person = Ember.Object.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
.
