Observer

A memory management assistant. The expected usage is that an Observer instance will be the only thing that holds strong references to some collection of objects; once the Observer instance is no longer strongly-reachable (can be garbage collected), then neither will the collection of objects that it references.

An implicit Observer is required when interacting with Sources, to facilitate "automatic" memory management. To create an Observer, either explicitly do so:

implicit object myObserver extends Observer

or mix one into the containing class:

class Worker extends Observer {
//do things that require an implicit Observer
}
