Class ContainerProxyMixin

public

Given 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:

    1
    2
    3
    4

    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 behaviour 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.
