  • All Implemented Interfaces:
    NodeController
    Direct Known Subclasses:
    LocatableNodeController
    public class BasicNodeController
extends java.lang.Object
implements NodeController
    A basic node controller implementation, intended for use as a controller for graphs containing only one node type. This class can also be subclassed to control a specific type of node in graphs that have multiple node types.
