Container Class packages/container/lib/container.js:7


PRIVATE

A container used to instantiate and cache objects.

Every Container must be associated with a Registry, which is referenced to determine the factory and options that should be used to instantiate objects.

The public API for Container is still in flux and should not be considered stable.

destroy

private

A depth first traversal, destroying the container, its descendant containers and all their managed objects.

lookup

(fullName, options) Any private

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.
