Class Node

java.lang.Object
ca.spatial.table.Node
public final class Node extends Object
This class represents a Node in a topological network of connectivity between blocks. There should be a one-to-one matchup of Blocks to Nodes in a properly described topology. Use the Topology class to find Nodes by block index number.

Each Node contains a list of Edge objects. Edges indicate neighbour relationships.

      public Node​(int index, int area, Object label)
      Create a new Node object.
      Parameters:
      index - A unique ID that is usually the same as the index of the feature that this Node represents.
      area - The area of this block as a scaled integer.

    • addEdge

      public final void addEdge​(Node node, int length, float distance, boolean connectable)
      Add an Edge to this Node.
      Parameters:
      node - The neighbour Node.
      length - The length of shared edge.
