Interface Node

All Superinterfaces:

PropertyContainer, SemanticObjectContainer

All Known Subinterfaces:

CompositeNode

public interface Node
extends SemanticObjectContainer, PropertyContainer

A node is an object that is contained by a graph and is connected to other nodes by edges. A node has a semantic object that is its semantic equivalent in the application and may have a visual object which is its syntactic representation in the user interface.
