Field Details

SKELETON

public static final int SKELETON

Node.type == 0 -> skeleton node type == 1 -> red nodule type == 2 -> green nodule type == 3 -> mixed nodule

GREEN

public static final int GREEN

MIXED

public static final int MIXED

type

public int type

type == 0 -> skeleton node
type == 1 -> red nodule
type == 2 -> green nodule
type == 3 -> mixed nodule

area

public int area

nodeIndex

public int nodeIndex

nodeNumber

public double nodeNumber

nodeNumber represents the number shown on the nodule csv data to easily associate a nodule node with it's nodule number. If the node is not a nodule, the value defaults to -1. The notation is noduleNumber_noduleSubnumber, and the underscore is represented as a decimal.

distance

public int[][] distance

DEPRECATED 2d array where each element A_ij is the distance to the j'th node on the i'th iteration of dijkstra's. Each row is one iteration of Dijkstra's, we remove a used edge from the original graph and perform another iteration of dijsktra's to create a sample of possible paths. DEPRECATED

prevNode

public int[] prevNode

Constructor Details
