Class ContainerProxyMixin
publicGiven a fullName return a factory manager.
This method returns a manager which can be used for introspection of the factory's class or for the creation of factory instances with initial properties. The manager is an object with the following properties:
class
- The registered or resolved class.create
- A function that will create an instance of the class with any dependencies injected.For example:
let owner = Ember.getOwner(otherInstance);
// the owner is commonly the `applicationInstance`, and can be accessed via
// an instance initializer.
let factory = owner.factoryFor('service:bespoke');
factory.class;
// The registered or resolved class. For example when used with an Ember-CLI
// app, this would be the default export from `app/services/bespoke.js`.
let instance = factory.create({
someProperty: 'an initial property value'
});
// Create an instance with any injections and the passed options as
// initial properties.

Given a fullName return a corresponding instance.
The default behavior is for lookup to return a singleton instance. The singleton is scoped to the container, allowing multiple containers to all have their own locally scoped singletons.
let registry = new Registry();
let container = registry.container();
registry.register('api:twitter', Twitter);
let twitter = container.lookup('api:twitter');
twitter instanceof Twitter; // => true
// by default the container will return singletons
let twitter2 = container.lookup('api:twitter');
twitter2 instanceof Twitter; // => true
twitter === twitter2; //=> true
If singletons are not wanted an optional flag can be provided at lookup.
let registry = new Registry();
let container = registry.container();
registry.register('api:twitter', Twitter);
let twitter = container.lookup('api:twitter', { singleton: false });
let twitter2 = container.lookup('api:twitter', { singleton: false });
twitter === twitter2; //=> false
