public abstract class Node
extends Object
implements Disposable

A node within an Arez dependency graph. The node is a named element within a specific Arez system that forms part of the dependency graph.

The Node class can be extended by classes outside the Arez core package. Typically this is done when a collection of primitive types (i.e. Observables, Observers, ComputableValues etc) are aggregated to form a single abstraction within the reactive system.
