Class NodeWeightCalculator

java.lang.Object
  gdl.base.NodeWeightCalculator

public class NodeWeightCalculator
extends java.lang.Object

This class contains the core algorithm used for the space allocation of nodes of a graph: starting at a focus node, it tracks all connections and in the end calculates the weight of each node, that depends on the amount of children it has in the tree and the childrens sizes. Of Course the weight of each node is variable and depends on the currently selected focus node, so this weight calculation is performed always a new node is set to the focus.
