public abstract class Node
extends Object

An abstract base class for API level action nodes. Concrete instances of the actions should be created using their respective builders that inherit from NodeBuilderBaseImpl and implement the Builder interface. The public interface of Node objects is immutable. This way we can ensure at compile time that there are no cycles in the graph: once a node is built, it cannot get new parents. On the other hand, Node objects still keep track of their children, which are necessarily added after the parent node is built, so these objects are not really immutable and should not be used in a multithreaded environment without external synchronization.
