All Implemented Interfaces:

ImmutableGraphEltSet

public class VisibleLocality
extends Locality

VisibleLocality: Extends Locality to specifically handle the Nodes + Edges that are visible on screen. The visible attribute of the nodes + edges is set to true when they appear on screen, and false when they are removed from screen. Locality is used in conjunction with LocalityUtils, which handle locality shift animations.
